About three miles from Gettysburg, his advance brigade, Archer's, encountered the advance of the enemy. Archer and Davis were thrown into line, and, with some pieces of artillery from Pegram, the enemy were steadily driven back to the wooded hills this side of Gettysburg, where their principal force (since ascertained to be the 1st and 11th Corps) was disposed to dispute our further advance. Heth's whole division was now thrown into line: Davis on the left of the road; Archer, Pettigrew and Brokenbrough on the right, and Pender formed in his rear; Thomas on the left, and Lane, Scales and Perrin on the right. Pegram's and McIntosh's battalions of artillery were put in position on the crest of a hill overlooking the town of Gettysburg. Heth's division drove the enemy, encountering a determined resistance. About half-past 2 o'clock the right wing of Ewell's corps made its appearance on my left, and thus formed a right angle with my line. Pender's division was then ordered forward — Thomas' brigade being retained in reserve — and the rout of the enemy was complete, Perrin's brigade taking position after position of the enemy, and driving him through the town of Gettysburg. The want of cavalry had been and was again seriously felt. Under the impression that the enemy were entirely routed — my own two divisions, exhausted by some six hours hard fighting — prudence led me to be content with what had been gained, and not push forward troops exhausted and necessarily disordered, probably to encounter fresh troops of the enemy. These two divisions were bivouacked in the positions won, and Anderson, who had just come up, was also bivouacked some two miles in rear of the battle-ground. The results of this fight were for the Third Corps, two pieces of artillery and 2,300 prisoners, and the almost total annihilation of the First Corps of the enemy. Major-General Heth was slightly wounded. Brigadier-General Archer was taken prisoner by the enemy. Brigadier-General Scales was also wounded. Pettigrew's brigade, under its gallant leader, fought most admirably, and sustained heavily loss.
On the morning of the 2d July, Anderson was ordered forward to the front, and relieved Heth's division, extending to our right and along a crest of hills which faced the Cemetery Hill at Gettysburg,
