This was the first experience of the men under actual fire, and they behaved finely. When the outer works around Petersburg were attacked, June 15, Duncan’s brigade met the rebels, and did good service, driving the enemy before him. We had a number killed and wounded in this engagement. The rebels sought shelter in their main works, which were of the most formidable character. These defences had been erected by the labor of slaves, detailed for the purpose. Our forces followed them to their stronghold. The white troops occupied the right; and in order to attract the attention of the enemy, while these troops were manœuvring for a favorable attacking position, the colored soldiers were subject to a most galling fire for several hours, losing a number of officers and men. Towards night, the fight commenced in earnest by the troops on the right, who quickly cleared their portion of the line; this was followed by the immediate advance of the colored troops, the Fourth, Fifth, Sixth, and Twenty-second Regiments. In a very short time the rebels were driven from the whole line; these regiments capturing seven pieces of artillery, and a number of prisoners. For their gallantry in this action the colored troops received a highly complimentary notice from General W. H. Smith in General Orders. A few hours after entering the rebel works, our soldiers were gladdened by a sight of the veterans of the Army of the Potomac, who that night relieved our men at the front. A glance at the strong works gave the new-comers a better opinion of the fighting qualities of the negroes than they had calculated upon; and a good feeling was at once established, that rapidly dispelled most of the prejudices then existing against the blacks; and from that time to the close of the war, the negro soldier stood high with the white troops. After spending some time at the Bermuda Hundreds, the Sixth Regiment was ordered to Dutch Gap, Virginia, where, on the 16th of August, they assisted in driving the rebels from Signal Hill; General Butler, in person, leading our troops. The Sixth Regiment contributed its share towards completing Butler’s famous canal, during which time they were often very much annoyed by the rebel shells thrown amongst them. The conduct of the men throughout these trying scenes reflected great credit upon them. On the 29th of September, the regiment occupied the advance in the demonstration made by Butler that day upon Richmond. The first line of battle was formed by the Fourth and Sixth Regiments; the latter entered the fight with three hundred and fifteen men, including nineteen officers.
