Small
local and regional UDT/SEAL groups seem to be springing up in different parts
of the country. This is a good thing. The internet may have contributed to this
phenomenon; it certainly made organizing and communicating easier.
I do not know which was the first such group. Fifties
Frogs may have been the first to begin meeting apart from the Coronado and
UDT/SEAL Museum groups that had institutional sponsorship. The idea for the
Fifties Frogs originated with Robert Berry. Robert, Lloyd Crosby and I met at
Lloyd's home in
It would be interesting to know how many such groups there are now and to have
contact information on each of them. We could create a roster of all the groups
and publish that information along with announcements in the Fifties Frog
Magazine. Toward this end please send information on such groups to me at doncmarler@gmail.com or call 936 856
1609 or 409 594 8221.
This quarter we had an interesting communication regarding a "deathbed
type announcement." Mr. Harold L. Norris told relatives that he and others

DEMOLITION UNITS OF THE
ATLANTIC THEATRE OF OPERATIONS
This is a brief history of
the demolition units which operated in the Atlantic theatre, their early
training, their organization after basic training and advanced training, the
difficulties they encountered and the ultimate success in accomplishing their
mission. Their missions were unique in that they were assault demolition in
nature in contrast to the Pacific operations which were reconnaissance and
pre-assault demolition. Because they were the first demolition units to operate
in any theatre many problems were met and lessons learned which proved helpful
in determining training and policy in later operations. For these and many
other reasons it will be necessary to go back to the origin of the units, and
briefly follow them through the operations of the Atlantic Theatre.
The Naval Combat Demolition
Unit started in June of 1943 at
However, conditions were not
as desirable as they appeared. In the first place there was no training program
set up; no one had any idea as to what the mission might be. No one had the
slightest knowledge of what sort of obstacles might be encountered, what
pattern they might follow or the best method of destroying them, nor the
conditions under which demolition personnel might be called on to work. No
provision had been made for the construction of obstacles, supplying of
explosives, housing for the men or training facilities
for the unit. Clothing, obstacles, training, program, facilities and explosives
were therefore non-existent, yet the men were there and raining did go on.
Until ste (?) could be taken to get all of the
problems settled the first class spent from eight to twelve hours per day in
physical training and rubber boat drill and primacord
knot tying. The heat, sand-flies and
mosquitoes, food and living conditions were intolerable. From this first class
came four of the Naval Combat Demolition Units that were the beginning of the
demolition force of the Atlantic Theatre. A naval Combat Demolition Unit was
arbitrarily set as one officer and five men, primarily because it was determined
in training that the demolition personnel would work as a rubber boat crew and
that the number 6 would be the maximum number of men that could be carried in
one boat. Training and facilities at
The first unit sent from
“1. In addition to your
regular duties you will perform such
collateral duties as are assigned you by the executive
officer
or head of your department.
2. One of your
collateral duties is that of Officer of the Day at King’s Hotel according to the
following schedule: (This listed seven officers for the next
seven days, all of whom were Demolition Officers).
3. An additional
collateral duty is that of hard master according to plan and schedule to be
announced by verbal instructions of Officer in Charge.”
The first thought of the
demolition units after arrival was to set up an advanced training program.
While assuming collateral duties this was a difficult task. But they did fall
into the general work of the base acting as hard masters and watch standers,
while assigning the men to the various duties about the base. During the spare
time the units kept busy picking up road obstacles, roadblocks, concrete
masonry, etc., which has been placed as counter-invasion
measures at various points along the coast and hauling them to a small 200 yard
wide beach some eight miles from the Unit’s offices. There was
carried on an abbreviated training program and a beneficial bit of work in
demolition.
For advanced training it was
felt that additional training was needed in ship salvage, rocket disposal (i.e.
for the unexploded rockets which would be found on the beach), mine
recognition, and assault demolition practices of the British. Arrangements were
made and officers attended these courses and later taught the men. In January
as a result of attendance at the British equivalent of Naval Combat Demolition
Units known as COXE (Combined Operations Experimental Establishment) much
intelligence in the form of pictures and literature pertaining to obstacles
already placed on the coast of
After considerable difficulty
in procurement of a priority for steel, two bays of Element “C”
were constructed and placed on the aforesaid abbreviated beach. It was found by
experimentation on these that the best method of destruction would be the use
of charges, 16 of them placed at sixteen vital points of the structure, which
upon detonation would completely collapse the structure and leave no part of it
extending above the surface of the beach more than six inches. This proved very
successful in the few tests that were permitted. The greatest difficulty in
this process came in the attachment of the charges. From this difficulty came
research and design of the Hagensen Pack, a small
canvass sack, filled with two pounds of C2, which could be fitted and secured
to the angle iron regardless of its size or shape by means of a line and V-clot
hook of special design. Further and complete experimentation by the group on
this obstacle was interrupted when orders from higher authority came and split
the units into three separate groups. One group departed for Fowey,
The group with the Sixth
Battalion located in
By March the 25th of 1943,
{editor’s note: the date should have read 1944} the Beach Battalions were
ready to go to the marshalling area to await orders to invade. In the absence
of official word as to what part the Naval Combat Demolition Units would play
and what craft would be assigned if they were to be used, it was found
necessary to submit to higher authority a letter stating the capabilities of
the enemy to place obstacles on the beaches in a comparatively short time, and
the capabilities of the Naval Combat Demolition Units to destroy them either by
daylight assault or night pre-invasion demolition. This letter, together with
information of the tremendous increase in obstacles appearing on the beaches of
When it was determined that
there would be increasingly larger numbers of obstacles placed, that there was
a 25 foot tide change twice a day (which meant working in a tide that rose
approximately 1 foot every eight minutes) {editor’s note: This is an error;
it should have read 28 minutes.} and that the method of attack would involve
assault demolition, it became immediately apparent that larger numbers of
trained men would be necessary to reinforce the Naval Combat Demolition Units.
The training program at
During the early stages of
the training program the officers of each of the Naval Combat Demolition Units were
taking care of their units, procuring equipment, and organizing the men. There
was noticeable need for a commanding officer or a senior officer with the power
to make decisions or with authority to procure necessary items or determine
policy. When a commanding officer was requested two Lieutenant Commanders were
sent from the
After the training program
all units were removed to Salcome,
For the first time the
intelligence information was coming to the units from Naval
sources. New obstacles, new patterns of placement, and ever increasing numbers
of obstacles were being reported, as was predicted by the Naval Combat
Demolition Units. By this time, however, it was too late to change plans or to
give special training.
Repeated attempts to procure
transportation via LST or the equivalent for personnel and the tremendous
amount of explosives at this late date failed to produce results except for
Force “U”. All such ships were already assigned. Too, it was
impossible to procure the use of LCVP’s or the
equivalent. The only boats available
were the LCT (A)’s or LCT’s and those
were already assigned to transport troops and equipment. But the teams were
assigned as additional load to these and plans began for loading and moving to
the French coast. One group, the Force “U” which was to assault

The plan called for the
sixteen gap assault teams to land at H-hour plus three minutes, each clear an
initial 50 yard gap, (each gap was 200 yards from the adjacent one), widen and
extend the gap until it was continuous along a beach or joined the other gap.
This gap was to be clear from low tide to the high-water mark, or roughly would
be a gap fifty yards wide and 400 yards in depth. If the seaward band of the
obstacles were Element “C”, ten of the support team personnel were
to continue to assist the Naval Combat Demolition Unit – Army gap assault
team in the placement of the charges. The remaining personnel were to continue
to the succeeding bands and begin clearance. When the tide, which was at low
ebb and just on the rise, necessitated stoppage of the work, a green buoy was
to be placed at the flanks of the gap thus far cleared and two range markers of
different lengths were to be placed at the dune line in the center of the gaps
so that ships could be guided into the beach through the cleared gap. This
method of gap marking was inadequate but was a task which the gap assault teams
had to assume prior to leaving the
Preliminaries to the assault
were to be as follows: There were to be a total of 1000 to 1500 planes passing
continuously over the convoy enroute to
Naval gunfire from Battleships,
Cruisers, and Destroyers was to begin an hour or so before H-hour and continue
up until H - hour, which was to be at
The plan as set forth in all
probability would have worked successfully provided the timing of support for the
demolition units could have been followed. The original plan left no
alternative in case conditions of weather and sea slowed the operations.
Actually, what happened is as
follows: The LCT (A)s having the preloaded LCMs in tow and the demolition gap assault teams aboard
started crossing the channel. During the previous 24 hours the weather had been
excellent and the sea smooth; the weather now had taken a change for the worse
and the first five hours at sea were extremely rough, prompting the Supreme Commander
to order, at
In spite of all these
difficulties, the gap assault team had an orderly departure from the transport
area (this all being done without radio communication, as radio silence was to
be maintained until H – hour), and touched down almost in a perfect wave
at 0633 to 0635.
Almost without exception
every LCM was subjected to mortar, machine gun and French “88”
barrages, as the ramp was dropped. Those who were fortunate enough to get off
without being hit started to work immediately. It was clear that saturation of
the beaches by low flying bombers had [not] been accomplished on the beach or
above the dune line. No planes were seen going overhead nor were bomb craters found
on the beach in which Naval Combat Demolition Units could seek shelter from
their demolitions. There was Naval gunfire on the
pillboxes, but due to the particular angle of placement of the pillboxes at
their opening, the gunfire was rather ineffective. The massiveness of the
pillboxes gave adequate protection to the defending gun crews, who continually
harassed and fired on the demolition units as they frantically pressed on their
work. There was no evidence of unexploded rockets on the beach as was expected.
Inasmuch as the LCT (R)s objectives were not clearly
defined to the demolition parties, they may have had objectives inland
somewhere. At any rate, the LCT(R)s added little
toward neutralizing the small arms fire of the enemy entrenched along the beach
who were hindering the Naval Combat Demolition Units. Only three or four of the
32 DD Tanks were seen in operation, and these were seen in flames shortly after
they left the beach to go over the dune line. There were only six of the forty
– eight medium tanks operating; the others were either knocked out or
blown up so added no assistance to the Naval Combat Demolition Units. The infantry waves which were to proceed the demolition party were arriving and tripping
through the primacord ring mains or taking cover
behind the obstacles making it impossible for the charges to be fired.
Meanwhile the Naval Combat Demolition Units were under devastating enfilade
fire losing personnel by the score, but carrying on to the best of their
ability.
The obstacles encountered
were in three bands with three rows of obstacles per band, in a somewhat
consistent pattern, staggered and on ten to fifteen foot centers. They extended
from low tide to high tide extremities and were completely dry when work began.
A most difficult gap area had several bays of Element “C” joined
together or staggered, several rows of wooden ramps constructed of 10 inch
timber firmly jetted into the ground reaching a height of nine feet; posts
tetrahedrons of both concrete and steel construction, and hedgehogs six feet in
height of six inch angle–iron one-half inch in thickness, welded and
bolted together.
The least difficult gap area
had the wooden ramps, stakes, rails and hedgehogs in that order from seaward.
All of the obstacles had Teller mines (42), box mines or anti-boat mines
attached. These contained only a pressure device and were primarily meant to
blow up landing craft as they attempted too ram through the obstacles. The gaps
which were not completed, or which were not adequately marked soon became
filled with landing craft--LCMs, LCTs
and LCIs all with gapping holes in the bulkheads.
In spite of the extreme
difficulties, depleted personnel and powder, the demolition units were able to
clear eight complete gaps and two partial gaps all of which were clearly marked
and capable of receiving the succeeding waves bringing personnel and equipment.
The method of clearance on
the assault phase was accomplished by use of the two-pound Hanensen
pack. Each man was carrying about twenty of these two-pound charges, safety
fuse and detonator assemblies, and continued working until the rising tide
prevented further clearance. Post assault clearance, i.e. after the tide
receded, was accomplished with tank dozers, caterpillar tractors, and salvage explosives.
The mechanical equipment used was commandeered from the Rhino (Pontoon) Barges
and any other available sources. The Construction Battalion training which the
Naval Combat Demolition Units had had previously was of inestimable value in
this work. Removal of wrecked LCMs and LCVPs was accomplished by use of explosive hose and fifty
pound charges placed in the engine rooms and detonated by electric firing.
Complete clearance of the beach was attained by D-day plus two on

By H plus 2 hours an
incredibly short time for such a task, the Naval Combat Demolition Units had
joined their gaps so that there was a cleared frontage of over 700 yards
through which the subsequent waves could off-load their personnel and supplies.
The extremities were clearly marked until receding tide when demolitions were completed
and no obstacle remained after the first day.
Obstacles encountered were
scattered wooden ramps, eight unconnected bays or sections of Element
“C”, reinforced concrete posts, concrete tethrahedrons
and wooden posts. No mines were encountered in connection with the beach
obstacles. All obstacles were high and dry on arrival. The intensity of enemy
gunfire was not as severe as that of OMAH beach nor were
the obstacles so thickly patterned. The timing and execution of the operational
plans were much better which accounts for better results. In spite of the
shellfire from rockets, machine guns and “88” s, all hands worked
rapidly disregarding personal safety to complete their mission.
The essential difference in
the actual demolition operations was in the fact that electric firing was used
instead of safety fuse, giving a much better control in removal of the
obstacles. The fact that the men had a more pleasant trip across via LST and
the fact that they operated in faster and more maneuverable LCPs
probably added to the efficiency with which the they
completed their task. Casualties for the Demolition Gap Assault teams on

Doctoring the bull
This is an E. V. (Pat) Boyt yarn – as told to me by Zeke Zbranek..
This old Frenchman had a farm
out around Winnie. The farm was just down the road from the inter-coast canal
and at that time, the
Many folks in this area will
remember that bridge. It spanned the inter-coast canal as it ran east to west
between Winnie and
The bridge as you will
remember had tenders who were on duty at all times and when a tug boat would
come up the canal and blow it’s whistle, the
tender would swivel the bridge and swing it parallel to the canal, permitting
the boat passage.
Well this old Frenchman had a
bull and the bull got sick. Pat Boyt came by that day
and the farmer asked Pat to take a look at the bull. Pat inspected the bull and
declared him constipated – said the bull needed an enema.
Pat told the farmer to heat
some water and add a certain medicine to it. While the
water was heating the men were looking for some instrument with which to inject
the solution.
Finally, finding nothing
better, the men decided to use an old cow horn they found hanging on the wall.
The horn had been carved by the farmer and used for calling his dogs.
Well the men tied the bull
securely and inserted the funnel-like horn into the bull’s posterior. The
farmer’s wife brought the heated solution over – and the men,
unaware that the water had been heated to a boil and was still piping hot,
poured the horn full of the hot water.
When that hot water hit the
bull’s insides, he let out a bellow, bowed his neck and broke the
restraining rope as if it were spaghetti. He bolted, and in leaps and bounds,
headed down the road toward the intercoast canal. The
only thing unusual about the bull’s departure was that with each jump, he
was blowing the still inserted horn loud and clear.
The bridge tender on hearing
the horn blow, it sounding like a tug to him, swiveled the bridge. The bull,
charging up the road, evidently figured on crossing the bridge. Too late, he
found the bridge swiveled and plunged, with a splash, into the depths of the
canal.
Well the old bull drowned
from the canal water pouring into the open horn – and after that Pat
walked easy and kept a low profile when in vicinity of the old
Frenchman’s farm. He never made another diagnoses till the day he died.
