Numbers 67. Report of Lieutenant Colonel Henry S. Huidekoper, One hundred and fiftieth Pennsylvania Infantry.

SIR: Report of the action of the One hundred and fiftieth Regiment Pennsylvania Volunteers at Gettysburg, Pa., on July 1: On the morning of July 1, the one hundred and fiftieth regiment Pennsylvania Volunteers left camp near Emmitsburg, and about noon arrived on the battle-field at Gettysburg.

At the distance of 50 yards, a volley was poured into the rebels, which staggered them so completely that a second one was fired before an attempt was made to advance ore retreat. At this juncture, Colonel Wister ordered the regiment to charge, and led it in person. The rebels were utterly routed, and the colors of the One hundred and forty-ninth Pennsylvania Volunteers, which had been lost, were recaptured and restored to that regiment. The One hundred and fiftieth then fell back to the position from which it had advanced. The firing of the enemy, who was approaching in front of the corps, now became fearful, and the regiment changed front to rear to meet this new attack. The movement was made in perfect order, and then bravely did the men move to the front, following the color-sergeant, who rushed to place his standard on the small rise of ground in advance. Four companies again changed front to resist the flank attack, while the remainder of the regiment
