The ‘Devil Dogs’ of K Company, 3/5 Marines, were part of the legendary first Marine Division. They landed on the beaches of Guadalcanal in the Solomon Islands in 1942 – the first US ground offensive of the war – and were present when Okinawa, Japan’s most southerly prefecture, finally fell to American troops after a bitter struggle in June 1945. In between they fought in the ‘Green Hell’ of Cape Gloucester on the island of New Britain, and across the coral wasteland of Peleliu in the Palau Islands, a campaign described by one K Company veteran as ‘thirty days of the meanest, around-the-clock slaughter that desperate men can inflict on each other.’
