Saturday, 11th.—Rested again, though we were on the qui vive all the afternoon for a forward movement, the following order having been promulgated:—

Head-Quarters First Division, }
Department of the Susquehanna, }

Waynesboro', July 11th, 1863.

The Brigadier-General Commanding calls the attention of the command to the certainty of an early engagement with the enemy, and it is strictly enjoined upon Brigade, Regimental and Company commanders to attend at once to the condition of the arms and ammunition of the men under them.

No time is to be lost in putting the arms in perfect order and seeing that the boxes are filled with cartridges.

The rations on hand must be cooked and put in haversacks, so that no detention will ensue when the order to march is given; and also that the men may not suffer for food, when it is impossible for the supply trains to reach them.

By order of

Brig.-Gen. W. F. Smith.

It was found that few or none of us had the full complement of forty rounds of ball cartridges in good order, our stock never having been replenished since we left Fort Washington. Our ammunition pouches being of insufficient capacity we had been obliged to carry a portion of the cartridges in our haversacks, which, in common with the clothes we wore, had been repeatedly soaked by the rain.

About the middle of the afternoon we heard distinct cannonading, which proved to proceed from a skirmish arising out of the movement of General Meade toward the front of the enemy's position at Williamsport. Reports were current, and credited, of another general battle on yesterday, in which Lee had been worsted, and it was expected that it would be renewed to-day. Thus we had on the whole a good prospect of being present, and having a share, in the enactment of another scene in the glorious drama. Toward sunset came marching orders. We proceeded in the direction of Hagerstown. Some two miles or more out the road crosses the Antietam, the bridge over which the rebels had destroyed. We waded the stream without wetting our trowsers, and marched our feet dry before coming to a halt for the night, some three or four miles further on. We were now on the soil of Maryland, the bridge over the Antietam being a little south of "Masonandicksun"; and we accordingly set up the air of "Dixie" with Yankee variations and a rousing chorus.
