The First Assault on Vicksburg

All that night [May 18, 1863] McPherson's troops were arriving by the main Jackson road, and McClernand's by another near the railroad, deploying forward as fast as they struck the rebel works. My corps (the Fifteenth) had the right of the line of investment; McPherson's (the Seventeenth) the centre; and McClernand's (the Thirteenth) the left, reaching from the river above to the railroad below. Our lines connected, and invested about three-quarters of the land-front of the fortifications of Vicksburg. On the supposition that the garrison of Vicksburg was demoralized by the defeats at Champion Hills and at the railroad crossing of the Big Black, General Grant ordered an assault at our respective fronts on the 19th. My troops reached the top of the parapet, but could not cross over. The rebel parapets were strongly manned, and the enemy fought hard and well. My loss was pretty heavy, falling chiefly on the Thirteenth Regulars, whose commanding officer, Captain Washington, was killed, and several other regiments were pretty badly cut up. We, however, held the ground up to the ditch till night, and then drew back only a short distance, and began to counter-trench. On the graveyard road, our parapet was within less than fifty yards of the rebel ditch.
