'GI' was the designation of Allied convoys (together with a numerical and sometimes a literal suffix) plying the route from New Guinea to the Philippine islands group, and as such reciprocals of the 'IG' series (January/May 1945).
The convoys supported the US 'Love', Mike' and 'Victor' operations in the Philippine islands group, and began with GI.1 of 1/5 January 1945 from Hollandia, New Guinea, to Leyte island with the 11,615-ton E. J. Henry, 10,296-ton US Lake Erie, 10,448-ton US tanker Mission Purisima, 10,448-ton US tanker Montebello Hills, 10,448-ton US Rainier and 10,317-ton US Williamsburg. The last was GI.28 of 27/31 May 1945 with the US 9,950-ton commissioned transport General C. G. Morton and 8,920-ton US attack transport Sea Fiddler.
