caches and a network of pro-Southern informants. As a Colonel he commanded the 1st Northeast Missouri Cavalry. Throughout Porter's brief military career, his status as a regular army officer was not fully recognized by his adversaries, particularly Colonel John McNeil. Those serving behind Union lines were not recognized as legal combatants and were threatened with execution if captured. Though most of his activities were guerrilla operations or harassment, a few battles were fought. On June 17, 1862, near Warren or New Market, in Warren Township, Marion County with 43 mounted men, he captured four men of the Union regiment he found there. The prisoners' weapons and horses were taken, then they were paroled on their oath not to take up arms against the Confederacy until exchanged. Cherry Grove Moving northward through the western part of Marion, the eastern portion of Knox, and the western border of Lewis counties, Porter approached Sulphur Springs, near Colony, in Knox County. Along his route he collected perhaps 200 recruits. From Sulphur Springs he moved north, threatened the Union Home Guards at Memphis, picked up additional recruits in Scotland County, and moved westward into Schuyler County to get a company known to be there under Captain Bill Dunn. Union forces under Colonel Henry S. Lipscomb and others responded with a march on Colony. They overtook Porter at Cherry Grove, in the northeastern part of Schuyler County, near the Iowa line, where, with a superior force, they attacked and defeated him, routing his forces and driving them southward. Losses on both sides were minor. Porter retreated rapidly, pursued by Lipscomb, until his forces dispersed at a point about 10 miles west of Newark. Porter, with perhaps 75 men, remained in the vicinity of his home for some days, gathering recruits all the time, and getting ready to strike again. Memphis On Sunday, July 13, Porter approached Memphis, Missouri in four converging columns totalling 125–169 men and captured it with little or no resistance. They first raided the Federal armory, seizing about a hundred muskets with cartridge boxes and ammunition, and several uniforms (Mudd, see below, was among those who would wear the Union uniform, as he claimed, for its superior comfort in the heat, a fact which would later draw friendly fire and aggravate the view of Porter's troops as bushwhackers, neither obeying nor protected by the rules of war). They rounded up all adult males,
