Major White was already on his way to Springfield with his squadron. This young officer, hardly twenty-one years old, had won great reputation for energy and zeal while a captain of infantry in a New-York regiment stationed at Fort Monroe. He there saw much hazardous scouting-service, and had been in a number of small engagements. In the West he held a position upon General Fremont's staff, with the rank of Major. While at Jefferson City, by permission of the General, he had organized a battalion to act as scouts and rangers, composed of two companies of the Third Illinois Cavalry, under Captains Fairbanks and Kehoe, and a company of Irish dragoons, Captain Naughton, which had been recruited for Mulligan's brigade, but had not joined Mulligan in time to be at Lexington. Major White went to Georgetown in advance of the whole army, from there marched sixty-five miles in one night to Lexington, surprised the garrison, liberated a number of Federal officers who were there wounded and prisoners, and captured the steamers which Price had taken from Mulligan. From Lexington White came by way of Warrensburg to Warsaw. During this long and hazardous expedition, the Prairie Scouts had been without tents, and dependent for food upon the supplies they could take from the enemy. Major White did not remain at Warsaw to recruit his health, seriously impaired by hardship and exposure. He asked for further service, and was directed to report himself to General Sigel, by whom he was ordered to make a reconnoissance in the direction of Springfield. After a rapid night-march, Zagonyi overtook White, and assumed command of the whole force. White was quite ill, and, unable to stay in the saddle, was obliged to follow in a carriage. In the morning, yielding to the request of Zagonyi, he remained at a farm-house where the troop had halted for refreshment,--it being arranged that he should rest an hour or two, come on in his carriage with a small escort, and overtake Zagonyi before he reached Springfield. The Prairie Scouts numbered one hundred and thirty, so that the troop was nearly three hundred strong.
