On the 6th of July, 1864, General Early, with a portion of the rebel advance, crossed the Potomac, near Antietam, into Maryland, and made a raid on Washington. The Sixth Army Corps, including the Second Rhode Island, and Batteries C, D and G, were hurried to the defense of the Capital, and reached there just in season to save the city, and to aid in driving the enemy, who had approached within shelling distance, back into the valley of the Shenandoah. The pursuit of the rebels was continued, first under General Wright, and then under General Sheridan, who had been appointed to the command of the Department. In the Battle of Winchester, September 19, the Regiment behaved with great gallantry, and had nine men wounded, one mortally.
