"Guadalcanal" by Paul S. Newman. April-June 1964.

Paul Newman likely based this comic on the 1943 film Guadalcanal Diary or the eponymous nonfiction book. In the movie a single man is sent back for help. The trapped men actually sent a second soldier latter on, according to a US Naval Institute article.

(Note: Author of the book Guadalcanal Diary was a war correspondent on the island with the Marines covering the early part of the campaign. The US Naval Institute article about the incident uses new evidence--i.e., new in 1992 when the article was published--from a variety of US and Japanese sources including interviews of all three survivors and more than 50 soldiers of the 1st Marine Division regiment the patrol was from, and depositions of Japanese survivors.)

The only other survivor escaped at the end of the fight despite his wounds and enemy gunfire. The article says that "the last thing he (sic - the last survivor) remembers seeing was the Japanese hacking up the bodies of the soldiers as the position was overrun." Relief parties in the morning couldn't find where the patrol landed and never saw bodies on the beach as portrayed on the next page of the comic.

A week later after pushing the Japanese back from the area they found the patrol's mutilated remains near the landing including decapitated heads, a sergeant's headless torso strapped to a tree, and sand-covered mounds with severed arms and legs protruding.
