Thank you Ron for your reply. This escort sounds like the one.I can only presume that the escort was American.What the E.C or G.C. is i do not know.Merchant ships in this convoy were REPUBLIC. ERNEST J HINES.and SEA PIKE. Other escorts were LARDNER and ANTHONY and the BENNETT.This convoy sailed on the 6th August 1943.Other escorts joined this convoy on or about the 25th August,they were GLADSTONE. GOULBURN and PC 476.Weather the US escorts left this convoy on the 25th i don't know.The convoy papers i have states that the three merchantmen were the only ones in the convoy.
