Both Raider battalions were put into action at roughly the same time. On 7 August 1942, Edson's 1st Raider Battalion, assigned to the 1st Marine Division, landed on Tulagi in the British Solomon Islands Protectorate as the opening phase of the Guadalcanal Campaign. After the capture of Tulagi, the Raiders were moved to Guadalcanal to defend Henderson Field. One of their most notable engagements was the "Battle of Edson's Ridge", where the 1st Raiders, remnants of the 1st Parachute Battalion, and the 2nd Battalion 5th Marines scored a major defensive victory over Imperial Japanese Army forces on the night of 13–14 September. Out of the action both Edson and Major Kenneth D. Bailey were awarded the Medal of Honor, the latter posthumously. The Marine Raiders battledress was the M1942 Frog Skin pattern. In 1942, the Marine Raiders were the first unit issued with the M1942 Frog Skin pattern, which was reversible with a five-colour jungle pattern on one side and a three-colour beach pattern on the other side.
