I've been doing some casual research into the RN and RM shore parties that operated in mainland europe 1940. Apart from the large scale operation in Norway there were several smaller operations Operation Royal Marine, mining of the Scheldt, is difficult to obtain any information as to force strength and even if it had any Royal Marines or if it was purely a naval team. The Royal Marines Hook of Holland Company, raised as an emergency draft from Chatham division. This is fairly well documented. Next there was the Boulogne Royal Marines company again raised from Chatham Division, and the RN demolitions team. Both are well documented. There was also a RN medical team which landed but no information is forthcoming as to their strength, casualties or who led them. Calais company yet another rapidly formed RM unit from Chatham division is fairly well documented. Dunkirk is well documented but some information is conflicting. The SNO ashore Capt Tennant arrived in Dunkirk with 12 officers and 160 ratings and a signals detachment led by Lt Balfour consisting of a Yeoman of Sigs and 28 Signallers followed on the 30th by a Lt and 2 signalmen and 2 Telegraphists. But the SNO afloat Rear Admiral walker mentions leaving Dover on 29th in the company of two discipline parties each of 80 men. Are these the same as Capt Tennant's party? A third party No3 party is said to have been led by Lt Cdr Buthy consisting of another 120 ratings and a company of Royal Marines. I can only find one reference to the RM marines company and that is their deployment, nothing more. The other, naval section of the party, assisted the operation of the small boats, operated defensive weapons, forced reluctant civilian crews to take part in Dynamo and went ashore to assist in the embarkation of troops and provide security. But what of the Royal Marines? There was a maintenance party who operated in England and ashore in Dunkirk, they are fairly well covered. But a naval medical party who are briefly mentioned by army commanders but nothing more. At St Valery en Caux there was another naval embarkation party, in which some accounts by soldiers, the Royal Marines are mentioned, but information is scant. As for the naval parties at St Nazaire, Le Havre and other ports used to evacuate British and French soldiers I can't find anything. If anyone has information of any kind about these I love to know more.
