June 19, 1863.
Friday. Three more men knocked out to-day. One sunstruck and two wounded. The Rebs have men posted way back inside the works, with rifles having telescope sights, and it is these that do the mischief, rather than those in the rifle pits. Now that we are warned of these fellows, we must look sharp, and maybe then get a clip. This explains how a couple of balls whistled past me yesterday when no sound of a gun was heard.
