"Upon approaching Gettysburg I was directed to occupy the position in line of battle which had first been vacated by Pender's division, and to place one brigade and battery of artillery a mile or more on the right. Wilcox's brigade and Captain Ross' battery, of Lane's battalion, were posted in the detached position, while the other brigades occupied the ground from which Pender's division had first been moved. We continued in position until the morning of the 2d, when I received orders to take up a new line of battle on the right of Pender's division, about a mile and a half further forward. In taking the new position the Tenth Alabama regiment, Wilcox's brigade, had a sharp skirmish with the body of the enemy who had occupied a wooded hill on the extreme right of my line. . .Shortly after the line had been formed I received notice that Lieutenant-General Longstreet would occupy the ground on my right, and that his line would be in a direction nearly at right angles with mine, and that he would assault the extreme left of the enemy and drive him toward Gettysburg."

Commentary
Following is an extract from the report of R.H. Anderson, commanding a division in A.P. Hill's corps. It is an important piece of evidence in the study of the question of when Longstreet was expected to begin his attack. As this document shows, when Anderson was posted, sometime between 9:00am and 12:00pm on July 2nd, he had no expectation of an attack being eminent. It wasn't until after the skirmish involving the 10th Alabama that Anderson even learned that Longstreet would be positioning on his right.
