 That night, around 02: 30, apparently realizing that the battle was lost, Inagaki led his staff and most of the remaining survivors of his command — about 100 men — in a final charge on the Americans. In the charge, Inagaki and the remainder of his troops were killed almost to the last man. At sunrise on 23 January, the Americans secured the rest of the Gifu. Sixty-four men from the American 2nd Battalion, 35th Infantry were killed during the assaults on the Gifu between 9 and 23 January, bringing the total number of Americans killed taking Mount Austen to 175. The Americans counted the bodies of 431 Japanese in the remains of the Gifu's fortifications and 87 elsewhere around Mount Austen. Total Japanese losses in the Sea Horse and both Mount Austen battles were probably between 1,100 and 1,500 men.
