- Order of battle for Convoy SC-7
Convoy SC-7 was the seventh of theSC convoys , bound from Sydney,Nova Scotia across theNorth Atlantic to a number of British ports, mainlyLiverpool . [ [http://www.junobeach.org/e/4/can-tac-con-e.htm Canadian convoys] ] They were designated SC as their departure point was designated Sydney, Cape Breton in order to avoid confusion with Sydney in Australia . [The Allied Convoy System] The convoys formed part of the battle of the Atlantic during the Second World War. Large numbers of merchants travelled together with naval escorts to protect againstU-boat attacks. They were often slow, the merchants often only being capable of a speed of around eight knots and so were particularly vulnerable to attack. [The Allied Convoy System] This problem was exacerbated by a shortage of suitable escorts from either theRoyal Canadian Navy or theRoyal Navy in the early stages of the war. [ [http://www.naval-history.net/WW2CampaignsAtlanticDev.htm Battle of the Atlantic] ]Convoy SC-7 left Sydney on
5 October 1940 , consisting of 36 merchants initially escorted by the Canadian armed yacht HMCS "Elk" and the British sloop HMS "Scarborough". [ [http://www.convoyweb.org.uk/sc/index.html Convoy web] ] Having seen the convoy out of Canadian waters, "Elk" turned back on7 October leaving the convoy to spend three quarters of the crossing escorted by the lone "Scarborough". [ [http://www.convoyweb.org.uk/sc/index.html Convoy web] ] One of the merchants, SS "Winona" had developed engine problems and also turned back. [ [http://www.convoyweb.org.uk/sc/index.html Convoy web] ] The crossing was uneventful to begin with, the only casualty being the SS "Trevisa" which was straggling behind the main convoy and was torpedoed and sunk on16 October by "U-124". [ [http://uboat.net/allies/merchants/596.html Sinking of Trevisa] ]The main convoy was spotted the following day by "U-38", which sank the SS "Aenos". [ [http://uboat.net/allies/merchants/ships/599.html Sinking of Aenos] ] Further sporadic attacks continued that day and the following, despite the arrival of the sloop HMS "Fowey" and the
corvette HMS "Bluebell". The night of 18/19 October saw the successful use of thewolf pack tactics of Germany's U-boat fleet. Five U-boats; "U-46", "U-99", "U-100", "U-101" and "U-123" attacked en-masse, overwhelming the escorts, newly reinforced by HMS "Leith" and "Heartsease". [ [http://www.worldwar-2.net/timelines/war-at-sea/atlantic/battle-of-the-atlantic-index-1940.htm Timeline of World War II] ] They sank 16 merchants in a six hour period, bringing the total to twenty merchants sunk and a total tonnage lost of 79,592 Gross registered tons. The U-boats only broke off their attacks to interceptConvoy HX-79 that had arrived in the area. They went on to sink a further 12 ships from this convoy, for a total of 28 ships sunk on 18/19 October , making this the deadliest two days of the battle of the Atlantic. [ [http://www.worldwar-2.net/timelines/war-at-sea/atlantic/battle-of-the-atlantic-index-1940.htm Timeline of World War II] ] The surviving merchants were gathered up by the remaining escorts and brought into port several days later.Merchants
