About midmorning on the day of the battle, as he was leading a charge of the 2d Kansas Infantry against Col. Richard Weightman's Missourians, Gen. Nathaniel Lyon was stuck by a musket ball that passed through the chest. Slowly dismounting, the mortally wounded Lyon collapsed into the arms of orderly Pvt. Ed Lehmann. A granite marker (left), placed there in 1928 by the University Club of Springfield, MO., marks the approximate spot where Lyon was killed, commemorating the death of one of the Union's outstanding officers
