Report of enquiry into the loss of H.M. Paddle Minesweeper
GRACIE FIELDS
in Operation "Dynamo".
Sir,
With reference to Admiralty Letter.6245/40 dated
1st August 1940, be pleased to lay before Their Lordships the following report resulting from an enquiry held into the loss of H.M.Paddle Minesweeper GRACIE FIELDS on 29th May 1940.
2. Temporary Acting Lieutenant Commander A. C. Wicks,R.N.R., who was in command of GRACIE FIELDS, was interviewed on
21st September, 1940.
3. At about 2030, on 28th, when ship was in vicinity of
Middlekerk Buoy, she was subjected to attack by enemy bombers for about a quarter of an hour. Two bombs scored direct hits in the Engine Room, wrecking the control platform and bursting steam pipes.
(ii) Endeavour was made to shut off steam at the main stop valve on the upper deck near the funnel, but the valve could not be closed.
(iii) The explosion put the steering gear out of action by fracturing the nal and chain connection.
4. Fires were drawn, the Engine Room was flooding steadily and by the time access could be gained, there was about 6 feet of water in the compartment.
5. PANGBOURNE came alongside and took off all troops and crew of GRACIE FIELDS, except those required for taking her in tow.
6. PANGBOURNE towed GRACIE FIELDS till about 0200 when, sponsons being awash and Engine Room and Stokehold flooded to a depth of 10 feet, it was decided to abandon her. Tow was cast off and remainder of crew were taken on board PANGBOURNE.
7. The ship was then in about 10 fathoms and sinking.
Although it was not revealed when she actually sank, it seems, from the evidence, unlikely that she remained afloat more than about half an hour after being abandoned.
8. C.B.'s and S.P.'s not in use were in steel chest in
Captain's cabin, which was so wrecked that it was not possible to have them. Those in use were taken on board PANGBOURNE and landed at the port of arrival.

Enquiry into the loss of
H.M. Armed Yacht PELLAG II
in Operation "Dynamo"
CENTRAL
(27 SEP 1940
Sir,
REGIS
In accordance with Admiralty Letter N.L.6245/40 dated 1st August,
1940, be pleased to lay before Their Lordships the following report resulting from an enquiry held into the loss of H.M. Armed Yacht PELLAG II
in Operation "Dynamo".
2. Temporary Lieutenant F.W.R. Martino, R.N.V.R. was interviewed on
3rd September, 1940.
3. When PELLAG II was approaching Dunkirk at about 1000 on 31st May,
1940, she went to the assistance of a trawler which was aground. In her efforts to tow the trawler off, the clutch of Diesel Engine burnt out and the wire cable of steering gear parted. Effort to tow was then abandoned.
4. The hand tiller was rigged but could not be efficiently operated on account of the depth charge davit which prevented it passing the midship position. The ship could only proceed very slowly and the
Commanding Officer asked WORCESTER to take her in tow.
5. WORCESTER was leaving Dunkirk heavily loaded with troops and as she was being subjected to bombing attack and PELLAG II's defective steering made towing very difficult, WORCESTER took the Commanding Officer and men on board and cast PELLAG II off. An effort to sink the yacht was unsuccessful on account of aerial bombardment.
6. PELLAG II was, at 0600 on the 2nd June, found adrift by a party of Royal Engineers which, under Major M.C.A. Henniker, R.E., was making its escape from the French Coast in rowing boats. They boarded the yacht and managed to get the engines running. PELLAG II was making slow progress when at 0515 on 2nd June H.M.S. LOCUST closed and examined her. As the engines and steering gear were found to be defective, officers and other ranks were taken on board LOCUST and PELLAG II was taken in tow. Shortly afterwards, the tow parted. Two further attempts were made to tow her but as enemy aircraft were in the vicinity the Commanding Officer of
LOCUST decided to abandon her. An attempt to sink her by gun-fire was not successful, and the Commanding Officer of the LOCUST, states, in a written report he has sent to me;-"with the prevailing set of wind and
"tide it is Klams that she may have subsequently fallen into the hands of"
"the enemy."
7. S.P.'s and Charts were transferred to WORCESTER.

11. (111) Destruction of Asdic Gear.
Any method of firing the demolition charge from the upper deck means that it must have been previously 'primed', i.e. the detonator and primer are fitted to the main charge.
To do this by remote control would be extremely difficult and also liable to failure.
2.
With the danger of non-contact mines, near miss bombs, etc., it is considered dangerous to keep a charge permanently fitted.
3.
It is realised that there is a risk of failure when it is desired to destroy the Asdic gear and sink the ship since it may be impossible to get to the charge but this must be accepted rather than endanger the ship to the extent of keeping a charge in a fitted state.

Sir,
H.M. DESTROYERS LOST AT DUNKIRK.
Material - General Report on Behaviour of -
Having completed, as regards H.M. Destroyers, the enquiries directed by Admiralty Letter N.L. 6245/40, dated
1st August 1940, be pleased to lay before Their Lordships the following recommendations relating to this class of vessel:-
2. A/A Guns, Arc of Fire.
The mainmast should be removed to give a better ard of fire for A/A guns, the mast being replaced by a light metal
(gas-pipe) gallows to take the after end of the aerials. This fitting has been seen in vessels at Harwich and appears to be quite satisfactory.
3. A/A Armament.
The 4 barrel.5" guns should be replaced by 4 or more single barrel guns, as it is considered that better results would be obtained by 4 men laying single guns on the same target than by one man laying 4 guns on the target. The provision of
Oerlikon guns is most desirable, also of Bren guns instead of
Lewis guns. It was brought to light that in one destroyer;
where a number of Bren guns (brought on board by the Military)
were manned, considerable damage and loss was inflicted on enemy bombers which could not be done with the ship's A/A armament.
4. Searchlights.
Opinion regarding the position and size of the searchlights is varied. In the majority it is considered that the new large light on a high platform amidships is not warranted, especially as the control from the bridge is not very satisfactory. It is.
contended that a powerful searchlight with a limited arc, espcially ahead, is normally not of great value and that a smaller light
(e.g. the old 24") sited above the bridge and able to show up an object directly ahead would be of more value. The reduction in weight of the large searchlight and the mainmast should allow of a smaller light with shorter control system being placed higher up forward.
(ii) The existing searchlight platform is in a most suitable place for A/A guns and, if the searchlight were removed and the platform enlarged athwartship, the existing 3"
and/or pom-pem platforms could be removed and the A/A
armament mounted on modified searchlight platform.
1940.
A/
5.
Shields for A/A Guns.
It is considered that light shields should be provided for all A/A guns. However light the shield is, it has the effect of removing the feeling of "nakedness" from the guns' crew and undoubtedly gives a certain amount of protection against machine gun fire and splinters. The shields fitted locally in Minesweepers,
Corvettes, Trawlers, etc., at Harwich appear to be very suitable. LB

Report of enquiry into loss of
H. M. A.B.V. KING ORRY
in Operation "Dynamo".
Sir,
With reference to Admiralty Letter.6245/40 dated
1st August, 1940, be pleased to lay before Their Lordships the following report resulting from an enquiry into the circumstances attending the loss of H.M Armed Boarding Vessel KING ORRY on
30th May, 1940.
2. Commander J. Elliott, D.S.O., R.N.R., who was in command of KING ORRY, was examined on 20th September, 1940.
3. At about 1930 on 29th May, when ship was approaching
Dunkirk, near misses-about 30 feet from ship - from dive bombers shook ship violently, and a few minutes later, when about to go alongside, a second attack took place. The ship was yet more violently shaken by explosion of near misses:
(i) The steering gear was put out of action through damage to the Telemotor system.
(ii) These near misses burst steam and water pipes on
Starboard side, and also burst steam pipe in after steering compartment, the escaping steam preventing access thereto and thus, neither the secondary steam steering gear nor the Hand wheel could be connected up.
4. Whilst ship was endeavouring to go alongside, near misses from a third heavy attack, which gave the impression of direct hits, holed Starboard side below water line in a number of places, and blew in a port hole and deadlight about 6" above water line in Stokers mess deck. These holes were, soon afterwards, stopped. A fire, the cause of which is unknown, broke out in Stewards Quarters on Starboard side forward. This was quickly put out by Extinguishers, but water was subsequently played into the compartment from fire and bilge pumps.
5. At about 0030, when ship was proceeding, stern first, to sea she developed a heavy list to Starboard which became more serious as water continued to enter the Boiler room.
(ii) Whilst endeavours were being made to point ship's head to seawards, the list grew steadily worse, and at about 0200, when in a position on the North side of the Channel, she turned over on her Starboard side and foundered.
6. Although lighting had gone in some parts of the ship, main and auxiliary engines were running and all bulkheads were intact.

With reference to Admiralty Letter N.L. 6245/40
dated 1st August, 1940, be pleased to lay before Their
Lordships the following report on the loss of H.M. A/S Trawler
BLACKBURN ROVERS on 2nd June, 1940.
2.
At about 1600 on 2nd June, in the vicinity of
"T" buoy BLACKBURN ROVERS was hit by a torpedo, or struck a mine, and sank instantly (videreport on WESTELLA No. 23/22
A.B/40 of 17th September, 1940).
11116G
3.
Commander R.W. English, R.N. who was in
BLACKBURN ROVERS, and was severely wounded, has informed me by letter - - whilst on sick leave - that, although he is now well enough to be interviewed, his recollection of the event is not very clear.
It has not, up to the present, been possible to see Skipper W. Martin, R.N.R. who was in command of the ship.
4.
In view of the very clear account given to me by Chief Skipper Grove, R.N.R. of WESTELLA who witnessed the sinking of BLACKBURN ROVERS, and on board whose ship
Commander English and Skipper Martin were taken, I do not consider that there is anything to be gained by interviewing either of these Officers.
I am, Sir,
Your obedient Servant, above 11166/40 aBeatord

Report of Enquiry into the loss of H.M. M/S Trawler POLLY JOHNSON
MILITARY
BRAN
in operation "Dynamo".
6F OCT 1940
Sir,
With reference to Admiralty Letter N.L. 6245/40
dated 1st August, 1940, be pleased to lay before Their Lordships the following report arising from an enquiry into the loss of
H.M. M/S Trawler POLLY JOHNSON on 29th May, 1940.
2.
Skipper Lieutenant L. Lake, R.N.R. who was in command of POLLY JOHNSON was examined on 1st October, 1940.
3.
At about 1500 on 29th May when POLLY JOHNSON was secured to CALVI which was alongside the pier at Dunkirk and astern of GRENADE, she was subjected to a heavy bombing attack.
Splinters from near misses perforated the ship's port side with small holes just above the water line and put the 12 pdr. gun out of action.
4.
The ship was subjected to further bombing attacks during the next two hours but at 1700, with about 50 troops and some survivors from GRENADE on board, she proceeded out of harbour, being able to make only very slow speed.
5.
Engine and Boiler rooms were making water steadily and ship's pumps were unable to cope with the rate of flooding.
6.
At about 1830 midway between Middlekerk and Nieuport
Buoys when it was obvious that POLLY JOHNSON would not remain afloat much longer, Trawler ARLEY came alongside and took all hands on board.
7.
ARLEY then endeavoured to destroy POLLY JOHNSON by gunfire but failed and left her in a sinking condition in about
7/8 fathoms. It is considered, however, that she was unlikely to remain afloat for long.
8.
Although it was not possible to elicit full particulars of the damage sustained by this ship it seems, from the evidence, in view of the fact that water was fast entering the Engine and Boiler room that this compartment was flooding below the waterline as result of heavy underwater explosions.
The flooding was accentuated when draught increased to admit water through holes already made above the waterline.
9.
Secret Charts were burnt in the stokehold before ship was abandoned and all S.P's and C.B's were transferred to ARLEY
and landed at Dover.
10, is the desirability of these craft carrying a number of varying

A copy of N.O.i/c. Leith's No.15, dated 2/7/40
was received in D.0.9002/40.
As a result of this report, W.P.S., Newcastle was asked to obtain targets composed of bitumastic deck covering fixed both upon mild steel plates and upon wood. These were supplied by Messrs. Wailes Dove Bitumastic Ltd. Captain
EXCELLENT carried out firing trials on 15/8/40. The trial results, although promising, were not sufficiently so to warrant the adoption of this material for protective purposes.
(See EXCELLENT's No.X 1798/7 dated 19.8.40 in G.011567/40.)
It was then decided to try a coarser composition such as that used in cattle boats, but before tests could be made a report was received from D.S.D. (IA/AW & D) giving particulars of a similar material which showed greater promise, containing a coarse granite aggregate and using bitumen as a binder. This material is being fitted to merchant ships, but before adopting it in warships it was considered necessary to get EXCELLENT
to carry out firing tests which are in hand.

With reference to Admiralty Letter N.I. 6245/40 dated 1st August, 1940 be leased to lay before Their Lordships the following summary resulting from nquiries held into the loss of various minor war vessels in operation "Dynamo".
As most of the small craft affected in these enquiries were converted for aval purposes and in nearly all cases sank very quickly little information egarding material has been obtained.
The following general suggestions are made as the result of interviews ith survivors:-
(a) the watertight subdivision of these vessels is in most cases quite inadequate to provide sufficient flotation when a part of the ship is holed.
(b) light shields for guns and some protection for bridges are very desirable.
(c) alternative stowage for and means of destroying C.B.'s etc. when necessary is desirable - (Note In diesel engined vessels it is extremely difficult to destroy books by fire).
(a) Rod and chain steering connections between wheel and rudder are easily fractured by shock from explosions.
(e) More isolating valves easily accessible required in main and auxiliary steam systems.
(f) Cast iron main intake pipes for circulators are easily fractured by shock (In a number of vessels so fitted the pipes have been boxed in with cement to prevent this).

Decks of "Westward Ho".
The decks of this vessel have been treated with a Bitumastic position about 2" thick and I have noted that during the recent rations at Dunkirk, machine gun bullets have penetrated all steel and dwork wherever exposed, while at the same time bullets which have contact with the deck have merely penetrated this Bitumastic composition come in no case have they gone through. This would appear to be an teresting fact worthy of further consideration, observing that the ight of the Bitumastic composition is considerably less than steel otection and it would appear to have had a similar effect to bullet sisting steel.
I have had no opportunity of conferring with the Officers of stward Ho but a coxswain informs me that the whole ship's company are of inion that the treatment of these decks have saved innumerable lives.

"Westward HO" - Treatment of Decks.
Further to my suggestion of 12/6/40, I have now had an opportunity of conferring with ship's officers.
The general opinion would appear to be that everyone was far too busy to note at the precise time of machine gunning the exact effect of bullets, but it was noted that no bullets penetrated the decks, yet they did penetrate ship's side and upperworks causing wounds to ratings after penetration.

Sir,
Be pleased to inform Their Lordships that I have, in compliance with Admiralty Letter N.L. 6245/40 dated 1st August, 1940, completed the enquiries into the circumstances of the loss of H.M. Ships engaged in the evacuation of the British Expeditionary Force and Allied Forces from Dunkirk with the following exceptions:-
H.M.A/S Trawler THURINGIA, M/S Trawler THOMAS BARTLETT, and Tug ST. ABBS.
2.
None of the Senior or other surviving officers of these vessels has yet been available for interview and I submit for Their Lordships'
consideration my opinion that in view of the large number of similar craft whose loss I have investigated, I do not consider any good purpose will be served by continuing these enquiries.
3.
The two surviving officers of THURINGIA are serving in the
Northern Patrol, the Commanding Officer of ST. ABBS is at Greenock and the Commanding Officer of THOMAS BARTLETT is on sick leave.

No mention is made in the Admiralty Dover's Report concerning the part played by the "ST. SEIRIOL" a small passenger steamer belonging to the Liverpool and North
Wales Steamship Co. Ltd.
The Minister of Shipping, in his broadcast about the
Dunkirk evacuation, specially mentioned the Chief Officer of this vessel who made two trips in the "ST. SEIRIOL" to
Dunkirk and spent the whole of one night in a Lifeboat picking up survivors from another ship which had been sunk. He and his boat's crew rescued 150 men. In consequence of his efforts he became partially paralyzed in the legs and could take no further action in the evacuation.
His action was outstanding and calls for some recognitior
