After over a decade-long drought, the Hamilton Tigers won the Grey Cup championship game in 1928, 1929 and 1932. The 1941 season saw the Tigers suspend play for the remainder of World War II. The Hamilton Tigers folded, largely because a number of players had gone into the armed services. It is believed by some that the failure of the Tigers is what caused the IRFU to be dissolved, and the Eastern Rugby Football Union (ERFU) to be formed. Because of the absence of the Tigers, a new club called the Hamilton Wildcats were formed to play in the ORFU in 1941. The Wildcats were given permission to use players from the Hamilton Tigers, but not the traditional black and yellow colors of the Tigers. In 1943, the Hamilton Flying Wildcats, stocked with Royal Canadian Air Force personnel, won the 31st Grey Cup.
