Nineteenth Brigade - Fourth Division - Army of the Ohio
Colonel William B. Hazen

This brigade reached the battlefield at 9 p.m., April 6, 1862, and bivouacked, on the right of the division, south of the siege-guns battery, in the following order: Ninth Indiana on the left, Sixth Kentucky on the right, and the Forty-first Ohio in reserve. The brigade advanced at 5:30 a.m., April 7, and became engaged about 8 a.m. at Wicker Field. The Ninth Indiana lost heavily at the house on the north side of the Peach Orchard. The brigade then advanced to the Wheat Field, where a battery was captured and its guns spiked by the Forty-first Ohio. This advance was held only a few minutes, the brigade falling back somewhat disorganized to Wicker Field, from which it advanced at 2 p.m. across the west side of Peach Orchard and took position near Prentiss's headquarters. It was not again engaged, and bivouacked there Monday night.
