Ports of call for GZ convoys

The GZ convoys were a series of Caribbean convoys which ran during the Battle of the Atlantic in World War II.^[1]

They take their name from the route: Guantanamo, Cuba to Cristóbal, Colón, Panama^[1]

Overview

The GZ series was the reverse of ZG series that ran from 31 August 1942 until 17 May 1945. There were 139 GZ convoys, comprising 1,151 individual ship listings. The escort ships for these convoys are not listed in the reference cited. Almost all ships listed in a convoy made the complete trip between Guantanamo and Cristóbal with a few going to Kingston, Jamaica, or Cartagena, Colombia.^[1]

The series started with GZ 1 through GZ 139 with only 1 convoy being cancelled, GZ 31. There are only two ships listed as being lost, and the losses were not due to enemy action, one grounded and broke in two and the other was from a collision.^[1]
