Additional Biographical Material:
Fifteen Years Ago, or The Patriotism of Will County - by George H. Woodruff:
  Henry A. Sperry, son of Merritt Sperry, of Manhattan, was a member of Co. B. 20th regiment.  After being wounded at Shiloh and Britton’s Lane, and following the ragged and blood stained flag of the 20th, through eight battles, he received wounds at the battle of Champion Hills, which resulted in his death near Vicksburg, the 18th of May, 1863, in the 21st year of his age, greatly mourned by his friends and acquaintance, but leaving behind him a proud record.
