The Guadalcanal campaign was unique among the amphibious operations conducted in the Pacific during World War II. Neither the United States nor Japan enjoyed the overwhelming naval superiority which in almost every other case ensured victory for the greater force. Relative equality made the naval forces of each side a constant threat to the supply lines of the other. Consequently, both sides relied upon the high-speed transport, converted destroyers like "Stringham", which were well armed for transports and fast enough to evade more powerfully armed warships. While the contribution of the larger elements of the American fleet cannot be overlooked, the struggle for Guadalcanal was to a great extent the battle of the high-speed transport. "Stringham" and similar high speed transports succeeded where their Japanese counterparts failed. They kept the marines supplied.
