The Battle of the Bloody Ridge was fought from 12-14 September, 1942. It saw the Allies, mainly consisting of men from the United States Marine Corps, successfully beat back the attacking Japanese. Behind them was Henderson Field, an important airfield that the Allies had captured earlier in the Guadalcanal campaign. The attack was as close as the Japanese would ever come to taking Henderson Field.
