The submarines arrived off Makin early on 16 August and put the Raiders ashore early the next morning. Unfortunately for the Americans, the premature discharge of a rifle by one of the Marines destroyed the element of surprise. Carlson's Raiders then moved inland and engaged the Japanese troops on Makin Island, virtually wiping them out. Following Japanese air strikes, Carlson decided to withdraw, but rough seas and the failure of outboard engines capsized a number of the boats and stranded Carlson and some 120 Raiders ashore, most of them without their weapons. Fearing he was surrounded, Carlson considered surrender and even sent out a patrol with a surrender note.
On the morning of 18 August, Carlson led a patrol inland and discovered 83 Japanese bodies. Utilizing rubber boats and dugouts made by local peoples, most of the remaining Raiders had returned to the submarines by 11:00 that night. In the raid, the Japanese lost perhaps 160 dead; the Marines had 19 killed and 9 missing. The 9 Marines evaded capture with help from locals until their food ran out. They surrendered on 30 August. The Japanese then took these men to Kwajalein and beheaded them as war criminals. The Raiders had fought well, and Sergeant Clyde Thomason, who sacrificed his life to save several comrades, became the first enlisted Marine in World War II to win the Medal of Honor.
Although the raid did divert attention from Guadalcanal, it also taught the Japanese that they needed to strengthen their defenses. As a result, they heavily fortified Tarawa, which witnessed one of the bloodiest Marine landings of the Pacific War 16 months later.
In 1943, Hollywood produced a movie about the raid, entitled Gung Ho! and starring Randolph Scott. Between 2000 and 2001, the remains of the 19 dead Raiders were returned to the United States. Thirteen were interred at Arlington National Cemetery.
