The 5th Division landed on beaches red 1, red 2 and green 1 at the base of Mount Suribachi on 19 February 1945 on Iwo Jima. The division sustained heavy initial losses, so much so that by that afternoon, the 26th Marine Regiment (26th Marines) had to be released as the division reserve. On 23 February, two American flags were raised on Mount Suribachi by members of the 28th Marine Regiment (28th Marines). The 5th Division would fight on Iwo Jima from 19 February until 26 March where they would sustain 2,482 killed in action, 19 missing in action, and 6,218 wounded in action. This was the highest casualty rate among the three Marine divisions involved in the invasion. The 5th Division began loading onto ships on 26 March, finally leaving Iwo Jima on 27 March 1945 sailing for Hawaii.
