The first was EWC.1A of 6.7 June with the 695-ton British Crewhill, 646-ton British Cushendun, 581-ton British Donaghmore, 361-ton Dutch Erna, 640-ton British Gem, 297-ton British Hawarden Bridge, 631-ton British Moelfre Rose, 486-ton British Rockleaze, 1,224-ton British Stuart Queen and 632-ton British Wallace Rose escorted by two British warships in the form of the paddle-wheel coastal auxiliary anti-aircraft vessels Goatfell and Ryde. The last was EWC.2C of 23 June with 22 vessels including the 471-ton British Glen, 194-ton British George D. Irvin, 515-ton British J.F.V., 311-ton British Lowestoft Trader, 420-ton British Moorlands, 374-ton Dutch Njord and 577-ton British Topaz.
