The "Galloping Horse" is the American nickname for a series of kunai grass covered hills and ridges inland from the north coast of Guadalcanal.
From the air, the feature resembles the shape of a galloping horse, with the Matanikau River forking around it to the north and south. To the east of Galloping Horse is Sea Horse, The Gifu and Mount Austen.
After the Japanese Army failed to penetrate the American perimeter on Guadalcanal, the Japanese 228th Regiment, 3rd Battalion commanded by Major Haruka Nishiyama and elements from the 230th Infantry Regiment dug into this area prepared to fight a defensive battle at this location using defenses including machine guns, mortars and infantry. By January 1943, the Japanese were weakened from disease and poorly supplied.
During early January 1943, as the Battle of Sea Horse was concluding, U. S. Army soldiers cleared a trail from the Matanikau River to Galloping Horse to eliminate the Japanese defenders in the area. On January 10, 1943 the Battle of Galloping Horse began at dawn and lasted for three days. At least 170 Japanese were killed and fewer than 100 Americans killed in the area. Mopping up operations continued until January 22, 1943 with an estimated 400 Japanese killed. The remaining Japanese including Major Nishiyama escaped further to the west.
