“MAR 8, 1961: The Guatemalan Workers’ Party [Partido Guatemalteco del Trabajo] (PGT) issues a denunciation of continued plans to invade Cuba. The Party reports that the Retalhuleu base is the site of a great movement of planes, ‘including daily flights between Guatemala and the Guantanamo naval base.’ The document adds that the port of Champerico has received 200 tons of bombs, explosives, and arms from an American ship that were taken immediately to the training bases in Retalhuleu and the Helvetia finca [farm/estate].”
