THE HUNLEY'S DEPTH GAUGE IS TO THE (LEFT) PORT SIDE
OF THE COMPASS SHOWN HERE
Mon, 18 Apr 2005
On the night of February 17, 1864 between 8:45 and 9:00
P.M. the Confederate States Submarine H L Hunley rammed a 135 lb. Package of
black powder into the hull of an enemy ship, The U.S.S. Housatonic. The impact
threw the eight man crew forward, disrupting all uniformity of the hand cranking
cadence at the moment of the sudden slamming stop. Crew members aboard the
Housatonic stated “ About one minute after she (Hunley) was close alongside the
explosion took place, the ship sinking stern first and heeling to port as she
sank. “ “The torpedo struck the ship forward of the mizzenmast, on the
starboard side, in a line with the magazine.” The combined explosion of the
Housatonic’s powder magazine and the Hunley’s torpedo practically blew the
backend of the Housatonic off. The 207 ‘ Steam sloop was totally sunk in five to
The impact to the partially submerged submarine caused
damages that have not totally been assessed.
One of the more recent clues of what happened to the Hunley
that night is the depth gauge. Researchers believe that the thin glass of the
specially built depth gauge shattered sometime during the concussion of the
blast or from Commander Dixon falling against it. During the removal of
material from the interior of the sub, Scientist discovered the heavy mercury.
Maria Jacobsen, senior archaeologist on the Hunley project stated, "When we
found George Dixon, literally at his feet was a pool of mercury."
H. L. Hunley
archaeological and conservation teams successfully completed the excavation of
the central compartment of the submarine.
Two pieces of thin (5.6 mm in diameter) glass tubes were found concreted to the
submarine's hull near Lt. Dixon's post. These were the remains of the
submarine's depth gauge."
The depth gauge found (December 7, 2001) in the forward
section of the crew compartment connected to the hull on the upper port side
near a seacock when opened allowed water to enter through a pipe that pushed
against the heavy metal Mercury. As the Hunley dove beneath the surface the
increased water pressure moved the mercury in the glass tube allowing the
Captain to read the scale and determine his depth. Officials have stated that “
the depth gauge, which was nearly 3 feet tall with piping running down the
portside hull and halfway back up, was mounted to a board with markings
indicating the sub's depth.” Hunley senior conservator Paul Mardikian said
according to Brian Hicks of the Post and Courier, “ the technology could have
been inspired by or copied from any number of pressure gauges in use with
boilers or the like in the mid-19th century.” He goes on to say, “The depth
gauge idea was at least a century-old by the time the Hunley sailed.
Contemporary reports of David Bushnell's Turtle say the Revolutionary War-era
submersible carried some sort of depth gauge.”
Hicks states in his article that..” Jacobsen said the way
the gauge fits into the sub makes it appear that it was built specially for the
Hunley. Originally, the Hunley was designed to tow a contact mine behind it,
dive under ships and pull the mine into the enemy ship's hull. The depth gauge
would have been an important tool for that sort of navigation.”
Because the CSS H L Hunley had sunk on at least two
previous occasions, the second time from pilot errors by H L Hunley himself
while diving, General Beauregard had ordered that the Hunley only be used as a
“David”. There was to be no more diving and all operations were to be
conducted “semi-submersed”. For this reason, it is believed that the Hunley no
longer needed her depth gauge unless Commander George E. Dixon had plans of his
The Hunley scientists have stated that according to Hicks ”… the Hunley's depth
gauge is in worse condition than most artifacts they've found in the submarine.
Besides the broken glass and spilled mercury, the iron piping is heavily
corroded. That could have been caused by scouring of sediment pouring into the
sub, or could be some reaction to holding the caustic liquid metal.” "Getting it
out of the submarine was a scary ordeal; it is very fragile," Mardikian said.
Friends of the Hunley, Inc. have still not allowed a public viewing of the depth

Depth Gauge is a device
used to measure pressure and display the equivalent depth in water. It is a
piece of diving equipment often used by SCUBA divers.
Most modern diving depth gauges have
an electronic mechanism and digital display. Older types used a mechanical
mechanism and analogue display.
As the gauge only measures pressure,
there is an inherent inaccuracy in the depth displayed by most gauges that
are used in both fresh water and sea water due to the difference in the
densities of fresh water and sea water.
A diver uses a depth gauge with
decompression tables and a watch to avoid decompression sickness. A common
alternative to the depth gauge, watch and decompression tables is a dive

This gauge (Mercurial
Syphon Gauge) consist of a mortised iron siphoned shape tube the curve down
, containing a column of mercury, one leg of the syphon being shorter than the
other. Upon the mercury in the long leg floats a piece of iron, to which is
attached a cord, which extends through the tube over a pulley at the top, and
has fastened to its end a marker, which points to divisions on the adjacent
graduated scale. Steam being admitted at the end of the short leg, the pressure
pushes the mercury down and raises it in the long leg, and is, in rising,
carries the float up with it and causes the marker to descend. It will readily
be seen that the greater the pressure, the more the mercury will rise in the
longer tube, and the lower will fall the marker, thus indicating the exact
pressure of the steam.
The advantages of this gauge
are, its extreme simplicity and consequent reliability. It is not a new
invention, but one that has stood the test of time and experience. Those

It was lost in
act of torpedoing the U.S.S. Housatonic on Blockade Duty off Charleston
On the night of February 17, 1864, the United States
steamship – of – war Housatonic, on blockade duty off Charleston S.C. was sunk
by the first submarine successfully used in offensive effort. I am one of the
few persons, if not the only one now living, who saw that epoch-making craft.
The submarine boat was designed by Horace L. Hundley and
built under his supervision at Mobile, in 1863, by a man named McClintock.
While much has been written about it in a general way, the most detailed and
apparently accurate description, printed originally in the Houston (Texas)
Telegraph, was recently discovered in an old scrapbook.
“She was built of boiler iron and impervious to water or
air,” says the writer. “Her extreme length was about 30 feet, with a five or
six foot beam, and about six feet depth of hold. In general contour she
resembled a cigar, sharp at both ends. She was propelled by a screw, the shaft
of which ran horizontal along her hold, almost from stem to stern, and was
turned by the manual force of eight men seated along it on either side.
“The only hatchway was circular, about two feet in
diameter, with a low combing around it, which was placed well forward, and when
desired could be closed by an iron cap working on hinges and made airtight. In
the forward part of the cap was inserted a clear glass bull’s eye, through which
the pilot could see. She was provided with watertight compartments, by filling
or emptying which she could sink or rise, and to enable her to rise instantly
her ballasting of railroad bars was placed on her bottom,, outside of the hull,
and , by means of keys accessible to her crew, could be detached in a moment so
that she could rise quickly to the surface. Besides her rudder, which was of
the usual form, she was equipped with side paddles, or fins, which , like those
of a fish, served to guide her up or down with reference to the surface of the
“To prepare for action, a floating torpedo was secured to
her stern by a line more than 100 feet long, and, her crew having embarked, the
water tanks were filled till the boat was in equilibrium and almost submerged.
The hatchway was closed, the men revolved the shaft; the Captain or the pilot,
standing under the hatch, steered the boat, regulation at the same time, by the
action of the fins, the depth at which she would move.
“She could remain submerged for half an hour or an hour
without any great inconvenience to the crew, and on one occasion had been known
to remain under water two hours without actual injury to them, although no means
were provided for procuring fresh air, and from the moment the hatch was closed
the men, thus fastened in their living tomb, inhaled and exhaled continually the
atmosphere enclosed with them.
“The plan of attack proposed by the inventor was to dive
beneath an enemy’s ship, hauling the torpedo after her. Its triggers would
thus press against the ships bottom, explode the torpedo and inevitably sink the
ship. “Not anticipating an early opportunity of using the dangerous vessel
against the fleet of Farragut, General Maury sent her by rail to General
Beauregard at Charleston, believing the waters of that harbor better suited to
her peculiar construction. Beauregard changed the position of the torpedo by
fastening it to the bow. Its front was terminated by a sharp and barbed lance,
so that when the boat was driven against a ship’s side the lance would be thrust
deep into the hull below the water line and thus fasten the torpedo firmly.
Then the boat could back off and explode it from a distance.
“General Beauregard’s call for volunteers to man this
dangerous craft was promptly answered by Lieutenant Payne, a Virginian, and
eight sailors. The evening set for the expedition the torpedo boat was lying
alongside the steamer, from which the crew had embarked. She was submerged till
the combing of her hatch alone was visible above the water. Her commander,
Payne, was standing in the hatchway in the act of ordering her to be cast off,
when the swell of a passing steamer rolled her over and sunk her instantly,,
with her eight men in several fathoms of water. Lieutenant Payne sprang out of
the hatchway as the boat sank from under him, and he alone was left alive.
“In the course of a few days she was raised and again made
ready for action. Again Payne volunteered, and eight men with him.
“The embarkation for their second attempt was made from Ft.
Sumter, and, as before, all having been made ready, Payne, standing at his post
in the hatchway, ordered the hawser to be cast off, when the boat careened and
sank instantly. Payne sprang out, two of the men following him; the other six
went down in the boat and perished.
“Again the boat was raised and made ready for action, and
her owner, Captain Hundley, took her for an experimental trip into Stono River,
where, after going through her usual evolutions, she dived in deep water. For
days the return of Hundley and her crew was watched for in vain. After a week’s
search she was found inclining at an angle of 60 degrees, her nozzle driven deep
into the soft mud of the bottom.. Hundley was standing, dead, at his post, a
candle in one hand, the other stiff, in a vain effort to unclamp the hatch.
Lieutenant George E. Dixon, of the Twenty-first Alabama Volunteers, finally
essayed, with eight men, to take her against the Housatonic.”
The fate of the warship was plain, but the fate of the
submarine remained a mystery until the wreck of the former was raised, more than
eight years later, in the summer of 1872. Then she was found hanging to the
rudder chains of the hulk. It was made plain, therefore that she had not
carried the torpedo in front, as Beauregard suggested, but had towed it astern,
as Hundley originally devised.. She had actually passed under the Housatonic and
was making her way aft to safety when her upper works caught in the rudder
chains of the victim.
By invitation of the contractor , a man named Maillefort,
who had done government work in Hell Gate, I was present at the raising
of the Housatonic wreck and saw the submarine in the position above described.
The torpedo exploded under the main mast of the ship and blew a great hole in

Sunken Iron-clads Curious Things Seen By Divers
The Charleston News in giving an account of the work of
wreckers in Charleston, says the iron-clad Housatonic lies in thirty-six feet
water, just over the bar, sixteen miles from the city. She rests on a hard
shell bottom and lies northwest and southeast, upright on her keel. The water
out here is beautifully blue and clear and the divers prosecute their work with
much less difficulty than at the Weehawken. Her decks, mast and rigging have
all been eaten away by the worms and little else is now left of her, but he huge
black hull. Her propeller shaft, chains and anchors, and a large portion of her
machinery have been hoisted from her by the machine and two of the smaller guns
composing her armament. The rest of them were taken up by the government
several years ago. The government has a buoy planted about three hundred yards
east southeast of the wreck, which enables the wreckers to guess pretty closely
as to her whereabouts. To render the matter a certainty, however, Captain
Soames when he leaves her to come up to the city, marks her position with a buoy
fastened to the centre of her hull. About twenty feet south of the wreck of the
doomed ship lies the hull of her destroyer, the Confederate torpedo boat.
She has been visited by the captain who reports her to be
lying bottom upwards, and seemingly in good preservation. There are no holes in
her hull and the wings of her diminutive propeller, now uppermost seem to be in
good running order. She did her work effectually. In the hull on the port
quarter of the huge ship is a jagged hole large enough to drive a carriage and
pair through. The heavy oaken ribs and thick planks are blown in with
tremendous power, and the Housatonic must have gone down with but little
preparation. Her diminutive but dangerous foe met with a similar fate, and the
two now rest in silence, side by side, at the bottom of the sea.

I find that the wrecks of the blockade runners are so badly broken up

is in an upright position; has settled in the sand about 5 feet, forming a bank
of mud and sand around her bed; the mud has collected in her in small
quantities. The cabin is completely demolished, as are also all the bulkheads
abaft the mainmast; the coal is scattered about her lower decks in heaps, as
well as muskets, small arms, and quantities of rubbish.
I tried to find the magazine, but the weather has been so unfavorable
and the swell so great that it was not safe to keep a diver in the wreck. I took
advantage of all the good weather that I had, and examined as much as was
The propeller is in an upright position; the shaft appears to be
broken. The rudderpost and rudder have been partially blown off; the upper parts
of both are in their proper places, while the lower parts have been forced aft.
The stern frame rests on the rudderpost and propeller; any part of it can be
easily slung with chain slings, and a powerful steamer can detach each part.
I have also caused the bottom to be dragged for an area of
500 yards around the wreck, finding nothing of
the torpedo boat. On the 24th the drag ropes caught something heavy (as I
reported). On sending a diver down to examine it, proved to be a quantity of
rubbish. The examination being completed, I could accomplish nothing further
unless it is the intention to raise the wreck or propeller, in which case it
will be necessary to have more machinery.

D. D. Porter's history of the war states explicitly that HUNLEY was sucked
into the hole blown in the Union ship,
and dragged down with it. He states clearly that she was found that way,
with all her crew drowned. "After the war it was discovered, on examination
of the wreck of the Housatonic by divers, that the torpedo-boat which
destroyed her had run partly into the opening made by the explosion, so that
all on board the David found a watery grave."

GENERAL: In answer to a communication of yours, received through
headquarters, relative to Lieutenant Dixon and crew, I beg leave to state
that I was not informed as to the service in which Lieutenant Dixon was
engaged or under what orders he was acting. I am informed that he requested
Commodore Tucker to furnish him some men, which he did. Their names are as
follows, viz: Arnold Becker, C. Simkins, James A. Wicks, F. Collins, and
Ridgeway, all of the Navy, and Corporal C. F. Carlsen, of Captain Wagener's
company of artillery.
The United States sloop of war was attacked and destroyed on the
night of the 17th of February. Since that time no information has been
received of either the boat or crew. I am of the opinion that the torpedoes
being placed at the bow of the boat, she went into the hole made in the
Housatonic by explosion of torpedoes and did not have sufficient
power to back out, consequently sunk with her.
I have the honor to be, general, very respectfully, your obedient

(the Torpedo man) Kochan
From: "evilmike2" Date: Tue, 26 Apr 2005
Subject: [CSS H L HUNLEY] spar
STAR WARS III
I followed up my fax sketch to the Lasch Center earlier this month,
with a phone call today to the archaeologist that was to help me with
the spar dimensions. I want to thank them for the time spent with me
First I was shocked to learn yesterday that FOTH Volunteer H. Frank
Aaron passed away in October at the age of 71. I tried to get him a
while ago but this time his wife answered. He was a perfect gentleman
from the old school (the kind of guy that would get up when a lady
got up from or came back to a table or in or out of a room and helped
he any way he could on my visits to the Lab as well as phone calls
and e-mails. I really miss him.
Perhaps a dose of reality here..... I'll get what I'm after shortly
and I added a few things. Now reality, answers to questions asked..
Positions of ballast tank valves? It looks like the handles come off
so they might not be in the way at that position. At this time they
are not sure which position the valves are because of the
covering. Time will tell.
Front hatch locking device is different the rear hatch. The device
itself is not attached to the hatch but appears to be in pieces
inside the sub. At this time they are not sure what it looked like so
they don't know if it was in the way ...Time will tell.
Snorkel position? ...same as tank valves too much covering it to
tell...Time will tell.
No, I didn't ask the one George wanted me to ask.... Can they crank it with
their feet? (Just one of the ones)
|Mike and Aaron at the Lasch Lab
I asked if I could relay the info and he had no problem. I had
fax back a disclosure form signed by me a while ago for some x-rays.
So from today's call it looks like the sub has to be clean to really
get a true picture of the way things are... Time will tell.

Discussions about the Collision, prop and sinking theories
that go with these occurrences by members of the CSS H L HUNLEY CLUB.
Before this discussion started Barry talked about
braking. How did the Hunley stop?
Picture courtesy of
I suspect there was quite a thud when the Hunley collided with the
Housatonic. Since the spar was not bent, it is reasonable to assume
that the forward momentum was converted into a moment that rotated the
submarine. The bow would be plunged downwards and the stern up. The
kinetic energy at 4 knots is sufficient to raise the entire Hunley up
about 9” but it was only rotated about its center of gravity.
Maybe the stern rose a couple of feet.
Does this seem reasonable? “Paul” <email@example.com>
“The crew was almost certainly braking,
i.e., cranking in reverse at the moment of impact in order to reduce their
momentum to avoid bending the spar or pushing it right through the wooden hull
of the Housatonic. I think it can be safely assumed that they had practiced the
technique of gently planting the harpoon point and backing off at least a few
times before going out after the Housatonic.
This wheel may have been part of a braking assembly. There does not
appear to be any significant gearing or other mechanism to support the
classification of this as a flywheel.
“The impact was a little harder than they intended
considering the mass of the Hunley and the inertia that had to be overcome in
order to reverse direction at exactly the right moment. Not an easy thing to do
in the heat of battle.
The Hunley’s drive train was not designed for reversing
direction. The original intent was to tow a torpedo under the target
ship, which involved only a straight-ahead movement. It’s quite
possible that the stresses involved in reversing direction finally
broke the drive train altogether.”
Reversing the prop would require overcoming the
momentum of the flywheel, something fairly easy for a trained crew operating
in concert, but definitely introducing a delay. I believe Maria has twice
mentioned some sort of brake on the flywheel. The photos we have show a
jumble of mechanics at the aft end, including the pump and the aft tank fill
valve, both of which have handles that extend back into the cabin so the man
in the last seat could easily reach them. I don’t see a brake there, but I
may be wrong. Michael (JVNautilus)
“Clearly, the drive train worked well enough in reverse
to support the changeover from the towed torpedo to the spar, but it could have
failed at any moment in either direction due to stresses built up over time. For
example, metal fatigue could have caused the some part of the drive train to
twist and bind up. Those of us who believe in Murphy’s Law know that it would
have chosen the worst possible moment to do that.”
”The point is that it (drive train) was not designed to reverse direction. Keep
in mind that the builders did NOT have welding technology at that point, only
brazing. So if the drive train (including crank, gears, prop shaft, prop, etc.)
was constructed using screw threads or fasteners it may very well have been
optimized for forward rotation. We may find out someday if the science team
takes it apart.”“Speculation is based on the theory that something had to be
damaged in order for the Hunley to have been still in the area of the Housatonic
roughly 45 minutes after the attack.” Barry
We know that there was a line or tether that ran from
the forward hatch attached to a spool and from there to a triggering device on
the Torpedo. The 135 lb Singer Torpedo was strapped to a barbed pipe and
sleeved onto the end of a 17’ +- spar. There was 150 ‘ of line around the spool
that would be fed out as the Hunley reversed after sinking the torpedo into the
hull of the Housatonic. Some of our discussions are around what would of
happened to the over 100’ of line left over after the explosion.
firstname.lastname@example.org, Tim Smalley wrote:
“Try dragging a 100 foot line from the bow of any boat with a propeller. You
get fouled every time.”
> evilmike2 : The fouled prop theory although possible and I
wouldn’t count it out,
reminded me more of Charlie Brown Flying his kite into the only tree for miles
“hunley_bar” <email@example.com> The
fouled line is a good theory, but I would think that IF they moved the Hunley
forward after backing away without winding up the broken cord; and IF they
fouled the prop, and IF the line were heavy enough not to break on its own (our
own boat had line-cutters in case we ran over the heavy lines of Maine lobster
traps, but anything less wouldn’t need to be cut as the shaft rotation alone
would have enough oomph to snap it), I’d think that as soon as they realized
what had happened, they’d have a crewmember in the water with a knife to remove
the problem. I’m inclined to agree with Mike’s point of view.
firstname.lastname@example.org If the torpedo lanyard fouled the prop, they may
not have realized it right away. Sure, if the crank completely froze, they would
have sent someone outside to assess the situation. But if the crank continued to
turn with some amount of extra resistance, it’s interesting to speculate how
much extra force they would have applied to it before stopping. Knowing what I
do about human nature, I think they might have applied enough force to do some
to the prop, rudder, and/or drive train.”
NOTE: McClintock, one of the designers of
the Hunley agrees with Barry’s assessment:
“...One difficulty which Mr.
McClintock very frankly pointed out was the uncertain action of the compass
in such a vessel...He also pointed out another requirement which he
had not succeeded in applying rather from want of means than from want of
skill, or from any great difficulty in the requirement [illegible]. He
states that when under weigh beneath the surface, it is quite impossible to
ascertain whether the vessel is progressing as there are no passing objects
by which to recognize the fact of motion; on several occasions when
experimenting with his boat they continued working the crank while all the
time the boat was hard and fast in the mud (“Report on a submarine boat
invented by Mr. McClintock of Mobile, U.S. of America,” PRO, Adm. Series
1/6236, File 39455).
“Keep in mind that Dixon and the crew may have been suffering from
all sorts of things and thus not at their best decision-making state
of mind. Assume that Dixon himself was the bosom, i.e., the person
directly commanding the crew to crank or stop. He had one or two
other things on his mind at the time. And when operating as a team,
the crew may not had the presence to mind to realize that even a
slight increase in resistance could be critically important.”
”Also keep in mind that it was dangerous to the open the hatches at
sea, where even a light chop could have allowed water to slosh into
the boat. It was something they did only when necessary. To reach
the point of sending someone over the side, significant damage had
to have already occurred. “ Barry
One of the questions ask to the group was: <<Is it possible that
the Hunley was hit by the Housatonic before she blew up. The Hunley was very
close to the Housatonic when she set off the torpedo.>>
“Impossible. The Housatonic was at anchor when the Hunley started
her attack run. Yes, the captain of the Housatonic was under orders to keep a
head of steam up. And yes, at some point the order was given to raise anchor and
”But even had she started to move, a steam sloop of war the size of the
Housatonic could not possibly have maneuvered herself into contact with the
Hunley, which was roughly perpendicular to her at the time.” Barry
Paul Howard <phoward333@y...>wrote: “With seven men turning the
crank (drive shaft) each individual is unaware of the total torque. If a rope
tightened around the shaft, each man may have thought, “The guy next to me is
slacking off and I have to try a little harder”. Their collective effort could
not be known. In addition, I would guess that they were almost out of oxygen,
which could have farther exasperated the situation. If they could survive 2
hours at rest, their cranking duration would be at best half as long. I know
that my breathing and heart rates doubles when on a treadmill.”
“ Suppose: They buttoned up the hatches 1 mile from the
Housatonic; cranked for 15 minutes, planted the charge, backed up 100-200’,
felt the detonation, cheered, then realized that if 90# of powder did that
what if the Housatonic’s magazine goes off? cranked backwards another couple
of minutes, waited for the coast to clear, signal with the blue light. At this
point they are almost out of oxygen and their thinking would be impaired. “
(We concur that the 90# torpedo was used when towing…but increased to 135# for
the final mission)
“Barry Rogoff” Paul, good point about how an individual turning
the crank would not
be aware of the overall torque. I think it’s simply instinctual behavior to work
harder when the going gets more difficult. It would have required training and
practice for the crew to be able to properly respond to a fouled prop and I
doubt that Dixon had time to train the crew that well.
Your point about oxygen deprivation raises another important question:
did the ventilation system work?
The currently accepted theory is that it didn’t work, or at least not very well.
That theory is based, in part, on various statements in the historical records.
I think one of the Confederate sailors captured before the attack said as much.
Alexander himself might have said something about it. (Too busy to look it all
up - sorry.)
My theory is that the ventilation system did work - on the surface. It’s based
partly on fact and partly on logic.
1. When the Hunley was recovered, air box/snorkel assembly was in place and the
bellows (air pump) and rubber ventilation hoses were found on board. Had the
ventilation system never been used, some or all of it would have been removed
and the openings sealed off. Why leave a bulky and potentially leaky system in
place if it’s not needed?

Club and the FOTH
2. Ventilating the boat on the surface was not a particularly difficult
engineering problem. Compared to all of the other problems that had to solved in
order to build a working attack submarine, getting fresh air inside the boat
would have been a piece of cake. It did not require any technological
I think the truth of the matter is that the ventilation system didn’t work very
well underwater. The length of the snorkels might lead one to believe that they
were intended to work with the hatches submerged. I don’t think so. I think
their height was intended to keep them above the waves in rough water, allowing
the boat to be
operable even in bad weather at sea. Barry
- "Barry Rogoff" wrote:I believe that the ventilation
system worked on the
surface and thus anoxia wasn't a factor. Other than the historical
record, there's not a single bit of evidence that it didn't work.
Having done the endurance dive, Dixon and the crew were well aware
of what the effects of oxygen deprivation felt like and someone
would have raised an alarm.
- "Tim Smalley" <email@example.com>Actually, the
historical record should be given weight. I expect that statements that it
didn't work were probably exaggerations. Perhaps the real question is how
well it worked. It's likely the endurance dive was done under special
controlled conditions, not after hours of cranking out to the Housatonic,
the adrenaline rush of an attack and aftermath and with the exertion of
cranking back. I think it's safe to say these guys were exhausted,
jubilant, and hurting and it's very possible they didn't recognize the
- "BR" Secondly, there's no reason to believe that the dive
planes were a factor. Yes, in normal operation, Dixon maintained
more-or-less neutral buoyancy and depended on the planes to control
the depth. But in this case, the mission was over and there was no
longer any reason to submerge the boat. For safety, he would have
pumped both ballast tanks dry and ridden as high in the water as possible
with the planes neutral or angled upward.
- "TS" Well, we do have Owlsey's statement that two crewman
were close enough together at each end of the cabin so that their remains
were co-mingled. It may be a leap to interpret this as two men on each
pump, but I think it's reasonable. If they were pumping like that water
must have been coming in. It's also certainly possible that Becker was
operating the air pump and the next guy working the water pump.
- "BR" Sure, it's possible that the boat could have
lost some buoyancy due to water leaking into the tanks, but I don't think it
could have lost enough to submerge without anyone noticing. It was Dixon's
responsibility to know the depth of the boat at all times and he was too
good an officer to get complacent enough to kill himself and the crew.
- "TS"Dixon would not have expended as much energy as the
crew but he would have shared in their excitement and he was very likely
tired. Even good officers make mistakes. We may not know if Horace Hunley
was a good officer but we know he made a fatal mistake.Michael
Hunley’s spar has a slight bend of a few degrees to the right, probably
due to the impact against the hull of the USS Housatonic when the
submarine was planting its explosive. Paul Mardikian, conservator for
the sunken Civil War sub, said X-rays of the area where the pole was
bolted to the Hunley also shows
damage, probably because of the strong impact. “We’ve got the memory of
the battle in the spar,” Mardikian said.”

CLOSE UP OF SPAR - FOTH
”Andy Hall” <firstname.lastname@example.org> Given
there’s no clear physical evidence of the cause of the boat’s loss, the
fouled-screw theory makes some sense. A fouled screw would have deprive the boat
of dynamic lift, and if the boat was trimmed slightly negative—or got that way
because of small leaks caused by the concussion of the torpedo --
then down she goes. Unfortunately it will likely never be proved, since the main
piece of evidence—the trigger line itself -
disappeared long ago.
For me the fouled screw theory makes a lot more sense than intentionally
bottoming the boat so close to the sinking. While Dixon undoubtedly would want
to wait for the tide or current to take him back to shore, I cannot imagine he
would have intentionally put the boat down there—the area immediately around
HOUSATONIC would almost certainly get very busy, very quickly after her sinking.
Trying to wait out the commotion so close to the sinking would be like a bank
robber “hiding out” at a table in the sidewalk cafe across the street—ballsy,
but with long odds of success.
As for the boat backing up directly away from the sinking, I suspect it did—that
would put them as far as possible from the blast, and expose the smallest
profile of the boat to the concussion.--------------> AH
Considering that the "Hunley" was built in Mobile, AL, along with
its predecessor, the "American Diver" and both vessels were larger
than the "Pioneer" built in New Orleans, LA, I would not sell
Southern technology short as many history books tend to depict.
First, both vessels were designed by the McClintock-Watson team, who
were innovative engineers. McClintock even experimented with
electric engines to power the "American Diver." This team chose
Mobile as opposed to other locations to set up shop after the fall
of New Orleans.
Second, both vessels were built at the Parks & Lyons Machine Shop in
Mobile, AL. This was likely a fair-size business, and apparently
had enough capacity to perform other workloads concurrently with the
Third, Mobile was a major port on the Gulf Coast. Other major ports
were Pensacola, FL, New Orleans, LA, and Galveston, TX. There were
two major fortifications guarding the entrance to the bay. Selma,
which had major industrial facilities, was upriver. There was
plenty of demand (Government, Military and Commercial) to attract
industrialists before and during the War.
I conclude that the Singer Submarine Corps (which was the main
backer of the "Hunley"), had the technical capability and industrial
capacity to produce war machines on par with the Union, but not
necessarily in the quantities that the Union could.
10) THE HUNLEY IS A
FORENSIC INVESTIGATION - THE COLDEST OF COLD CASES
Mardikian, senior conservator at the Warren Lasch Conservation Center in North
Charleston, S.C., examines paint on the crew bench recently removed from the
H.L. Hunley. The 40-foot, hand-cranked Hunley rammed a spar with a black powder
charge into the Union blockade ship Housatonic, Feb. 17, 1864. It was the first
sub to sink an enemy warship.
bench contains clues about the crew of the Hunley, including samples of
human hair that scientists can examine.
sub's sinking like a cold-case file
holds clues to what sank sub
CHARLESTON, S.C. - On the anniversary of its sinking, a scientist said it's
still not known what sent the Confederate submarine H.L. Hunley to the bottom,
but the vessel will eventually give up its secrets.
"There is no such thing as a
smoking gun when you are conducting a forensic investigation," Maria Jacobsen,
the senior archaeologist on the Hunley project, said Thursday.
"Archaeology is the perfect
forensic discipline. But in our case we have a very cold case. It's not 10 years
old. It's over 140 years old," she said. "I'm very confident we will know what
happened but it's a matter of time."
Thursday was the 141st
anniversary of the sinking of the first sub in history to sink an enemy warship.
The 40-foot, hand-cranked Hunley
rammed a spar with a black powder charge into the Union blockade ship Housatonic
on Feb. 17, 1864.
But the Hunley also went down
and was finally located off Sullivans Island in 1970 and re-located again in
1995. It was raised five years later and brought to a conservation lab at the
old Charleston Naval Base where it sits in a tank of chilled water.
Thursday evening, Confederate
re-enactors planned to march from Fort Moultrie on Sullivans Island to Breach
Inlet, where the sub began its ill-fated mission. They planned to throw wreaths
onto the water in memory of the sub's eight-man crew.
Earlier, journalists got a
chance to see the wooden crew bench removed from the submarine. The 18-foot
bench, fashioned of three sections of wood, is in remarkably good shape after
the sub sat on the ocean floor for decades.
Jacobsen noted there are few
signs that worms ate away at the wood.
That would indicate the
submarine filled with sediment after the sinking. Water rushing through would
have brought in more sea life, she suggested.
Paul Mardikian, the Hunley's
senior conservator, focused a magnifying glass on the bench to reveal a human
hair from one of the crewmen.
Scientists later found the faint
imprint of fabric on the bench, which had been painted with an oil-based paint.
Since the paint probably took a
long time to dry, the imprint could have been from the clothes of a crewman or
perhaps someone working on the sub before its voyage, said Kellen Correia, a
spokeswoman for the Hunley project.
More clues about what happened
after the sinking will be provided by examining the sediment excavated earlier,
Using Lead 210 dating,
scientists can narrow down to decades when something happened in the sub. Beyond
that, she said, scientists can get an even closer estimate by looking for pollen
inside the sediment.
"We are looking at the pollen
inside the layers. You can look at the pollen and that will give you an idea of
how things changed in a year," she added.
Mardikian said about 1,000
artifacts have been removed from the Hunley so far, including the shoes of the
crew which were freeze-dried as part of the conservation process.
He said scientists are working
three days a week on the sub itself and two days on conserving artifacts.
Scientists think they may find more artifacts in the heavy encrustations on the
sub found beneath the crew bench.
The remains of the Hunley's
eight-man crew were buried last year in a ceremony that attracted thousands and
has been called the last Confederate funeral.
Scientists are still determining
the best way to conserve the Hunley itself. The sub eventually will go on
display in a museum in North Charleston.
