and the rest of Hamilton's division in reserve behind the right.( 8) Van Dorn opened fire at 4.30 A.M. with artillery, but he did not advance to the real attack until about 8 A.M. It came from north of town and fell heaviest on Davies' division. His front line gave way, and later his command was broken, and some of the Confederates penetrated the town and to where the reserve artillery was massed. Stanley's reserves, however, speedily fell on them and drove them out with great loss. Then the attack came on Battery-Robinett, to the westward near the Union centre. Three successive charges were made in column on this battery and on the centre with the greatest determination, and much close fighting occurred until the last assault was repulsed about 11 A.M. (October 4, 1862), when the enemy fell back under cover beyond cannon-shot. Van Dorn had hoped to take Corinth on the 3d, and now, being repulsed at every point, he beat a retreat, knowing Grant would not be inactive. It was not until about 2 P.M. that Rosecrans ascertained the enemy had commenced a retreat.( 9) General James B. McPherson arrived, October 4th, from Jackson with five regiments, but too late for the battle. The engagement was a severe one; both armies fought with desperation and skill; the Union troops, being outnumbered, made up the disparity by fighting, in part, behind breastworks. The losses were heavy, especially in officers of rank. The Union loss was, killed 27 officers and 328 men, wounded 115 officers and 1726 men, captured or missing 5 officers and 319 men; grand total, 2520.(10) The Confederate loss (as stated in Van Dorn's report (11)), including casualties at Hatchie Bridge (October 5th), was, killed 594, wounded 2162, prisoners or missing 2102; grand total, 4858.
