A view from the top of Edson’s Ridge, also known as Bloody Ridge and Raiders Ridge, on Guadalcanal. The Lunga River anchor’s the ridge’s right flank. During the Battle of Edson’s Ridge, 12-14 September 1942, the Marine 1st Raider Battalion, led by Lt. Col. Merritt A. Edson, repulsed repeated attacks by the Imperial Japanese Army. Over a two-day period, the combined Marine forces suffered more than 250 causalities, while the Japanese Army sustained a staggering 800 casualties. Photo courtesy of the US Army/ Staff Sgt.
