On June 25, 1876, James Porter was likely killed by the
Sioux in the
Battle of the Little Bighorn under the command of George Custer. Regarding the Sioux engagement, historian Dr. Charles Kuhlman describes "the intervention of Lieutenant Porter in bringing up Troop "I" and posting it so that the first platoon stood massed above the entrance to the ravine. This placed it squarely in the rear of the warriors Calhoun and Crittenden were fighting, compelling them to seek cover and putting them out of the fight." Historian Thomas Hatch's research also surmises that because Keogh was found with Custer, "Lt. Porter actually commanded I Company on the battlefield. Every man from this company, known as the "Wild I" for its rowdy reputation, was killed." Porter's Company I was stationed on the east side of Custer ridge in the battle, where they were either in reserve, providing aid or cover, or "attempting a breakout during the last segment of the battle." Reports from Indian Agent
Valentine McGillycuddy, who spoke to
Crazy Horse, and Captain
Charles King, who interviewed several Indian survivors, both describe a single unidentified officer (not explicitly identified) from this east area who rode quickly through the Indian encirclement and nearly escaped, but looked back and saw a warrior pursuing him and committed suicide. On June 27, 1876, troops searching for Custer found some of the first evidence of Custer's demise in an abandoned Indian village when they "found the buckskin jacket of Lt. James Porter (Co. I) with a bloody hole on the side which covers the heart." Some parties speculated that Porter's head was also purportedly found in the village, but other sources claim this may have been another officer's (Sturgis) head, and that Porter's head was never recovered, but perhaps his torso was recovered. Among modern researchers and archaeologists, the consensus is that Porter's body was one of three officers' bodies (James Porter, James G. Sturgis, and
Henry M. Harrington) never identified, even though his death was verified by his bloody jacket, which was identified. The three missing officers were the only West Point graduates on the field besides Custer and Lt. Hodgson. After receiving pressure from the officers' families, General
Philip Sheridan gave special orders to his brother Lt. Colonel
Michael Sheridan to locate and properly bury the twelve officers' bodies to the extent they could be located. According to Nunnally's history, "[i]n 1910 Superintendent Wright set a stone marker for Lt. Porter whose body was never found. Wright had no evidence on the location of Porter's death and simply chose a random spot for its location." ==Legacy and family==
