 Only a few new batteries were complete by then, and emergency batteries were hastily built and armed with Civil War-era weapons, along with some new guns intended for Endicott batteries but mounted on old-style carriages, plus some smaller rapid-fire guns purchased from the United Kingdom.In 1901 the artillery batteries were redesignated, with the light batteries becoming numbered artillery batteries and the heavy batteries at the forts becoming coast artillery companies, all still part of the Artillery Corps.In 1907 the coast artillery companies were split off as the United States Army Coast Artillery Corps, with the light batteries becoming the Field Artillery.
