Waitt, Ernest Linden, History of the Nineteenth regiment, Massachusetts volunteer infantry , 1861-1865

At night the tired men of the regiment were gratified to learn that the following General Order had been issued:

Such orders as these, showing in a practical way the appreciation of the superior officers, did much toward making the hardships of active campaigning endurable for the men, and were bright spots in the dark days when there seemed to be nothing to be done but march, fight and stay hungry.

On the 27th the regiment moved to near Barnesville and on the following day to Monocacy Junction, near Frederick City, being the last of the army to reach this point, all the other corps having already assembled there. Here it was learned that Gen. Hooker had been superseded in command by Gen. Meade and on the next day the army was again on the march, each corps on a different route and all in search of Lee.

Before daylight on the morning of June 29th, Reveille was sounded and when the sun arose breakfast had been prepared and eaten and his rays shone on the regiments in line, ready for a march.

The men threw their muskets over their shoulders like men starting out to hunt, regardless of the manual of arms; others were at the right or left shoulder shift, while occasionally a man would carry his musket with the hammer resting on his shoulder. Another who had been slow at preparing came stumbling along, trying to fasten his roundabout with his musket under his arm and the barrel punching his file leader in the back. So the day's work began.
