"A survivor of the War of 1812 and one of the most active and remarkable men of the day when the late civil war broke out was Colonel William Christy. He was acting quarter master at Fort Meigs, and had charge of all the stores and flags there at that time."
"When the first gun was fired upon Fort Meigs, Harrison called him to his side and said, "Sir, go and nail a banner on every battery, where they shall wave so long as an enemy is in view." Christy obeyed and there the flags remained daring the entire siege."
"At an early age he [William Christy] went with his father to reside near the Ohio not far distant from Cincinnati. He was left an orphan at the age of fourteen years. He studied law and entered upon the duties of that profession in 1811. When war was declared, he joined the army under Harrison. That officer knew his father and kindly gave the son of his old friend a place in his military family as aide de camp...".
