The GAT convoys were a series of Caribbean convoys which ran during the Battle of the Atlantic in World War II.
They take their name from the route: Guantanamo, Cuba to Curaçao, Aruba and Trinidad
Overview
The GAT series was the reverse of TAG series that ran from August 1942 until 18 May 1945. There were 209 GAT convoys, comprising 3,696 individual ship listings. The escort ships for these convoys are not listed in the reference cited. Some of the ships listed in a convoy did not always make the complete trip between Guantanamo and Trinidad though. Some may have traveled as far as Curaçao, others would join at Curaçao and sail on to Trinidad, while others may have left to go to Kingston, Jamaica, San Juan, Puerto Rico or Puerto Plata.
Two convoys were successfully attacked by U-boats during 1942 and 1943, in which three ships were lost.
