Second Brigade - Fourth Division - Army of the Tennessee
Colonel James C. Veatch

This brigade, of four regiments, was encamped across the Hamburg and Savannah road, north of the Corinth road. It was sent April 6, 1862, to reenforce McClernand, and moved out along the Corinth road and formed in line behind Marsh's brigade at about 9 a.m. in the following order from left to right: Twenty-fifth Indiana, Fourteenth Illinois, Forty-sixth Illinois, Fifteenth Illinois. It became engaged at about 10:30 a.m., and at 11 a.m. was compelled to retire. The Twenty-fifth Indiana and Fourteenth Illinois fell back 200 yards, changing front to rear on left companies, and forming along the road that runs from review field past McClernanad's headquarters. A little later they retired to the right of Hare's brigade, where they held their position until after noon, when they fell back to McClernand's sixth line, where they engaged in Pond's repulse at 4:30 a.m., after which they joined Hurlbut in his last position on Sunday. The Fifteenth Illinois lost all its field officers and several captains at first position and retired at 11 a.m. to the Jones Field, where it was joined by the Forty-sixth Illinois in supporting Barrett's battery. These two regiments joined McDowell's left in the advance at 12 m. and continued in line until 1 p.m., when they retired - the Fifteenth Illinois to join Hurlbut, the Forty-sixth Illinois to its camp for dinner; later the Forty-sixth joined Marsh's command on the Hamburg road and assisted in the final action of the day and was with Marsh's command on Monday. The Fourteenth and Fifteenth Illinois and Twenty-fifth Indiana, under Colonel Veatch, formed the left of the Army of the Tennessee on Monday and joined McCook's right until about 11 a.m., when they crossed the Corinth road near Duncan's and were engaged in Review field and in front line until 4 p.m.
