The California Brigade protected the "Angle" during Pickett’s Charge

On July 3rd, the California Brigade was charged with defending the Angle during Pickett’s Charge. More than any other point along the line, the Confederate effort was concentrated on the Angle. The advancing Confederates were described as "an advance of an acre of soldiers," and when the 71st Pennsylvania, previously the 1st California, saw the large Rebel force approaching, they withdrew. The 69th and 72nd Pennsylvania, originally the 2nd and 3rd California, maintained their position after the 71st Pennsylvania's withdrawal and were crucial to the Angle's defense. The defense of the Angle was left in the hands of the infantry, the 69th Pennsylvania being the only close regiment, while neighboring batteries started to fall to Armistead's brigade.

The 69th opened fire heavily on the grey columns as the Confederates advanced forward. Many of the 69th's troops had six to eight loaded rifles hanging against the wall, ready to shoot, having accumulated weaponry. The 72nd Pennsylvania was 80 yards east of the Angle and had just been advanced from its reserve position. With a strong line of fire, the 72nd Pennsylvania Regiment helped the 69th and the two regiments of the California Brigade successfully stopped Armistead's brigade's further advance.
