There is evidence, however, that Custer was very much alive by the time he reached Last Stand Hill. Unlike almost all the other weapons fired that day, Custer’s Remington sporting rifle used brass instead of copper cartridge casings, and a pile of these distinctive casings was found near his body. There is also evidence that Custer’s battalion, instead of being on the defensive almost from the start, remained on the offensive for almost two hours before it succumbed to the rapid disintegration described by Sylvester Knows Gun and others.
