You have to keep an eye on those crafty Rebs. I came across some Reb a while back. They had what looked like a white flag flying when we approached. They fired at us. To make a long story short, we did capture the whole group and found out it wasn't a white flag. They were doing their laundry and hung their panties out to dry.
Did you see that in Shenandoah? It may have been General Jackson's cartographer, Jeremiah Hotchkiss, who had thought himself concealed at the time.
On the morning of 30 April 1862, Jackson sent Hotchkiss (with a bed sheet) to climb to the peak at the southern end on Massanutten Mountain. At 0100 that day Hotchkiss (and Company E, 10th Virginia Infantry) set off to climb the mountain. He reached the summit at 0500. From there he could observe the movements down in the valley and the Federal positions near Harrisonburg.
Hotchkiss waved the sheet, according to a prearranged code he and Jackson had decided upon, to inform Jackson of what was happening in the Valley. [Based upon the information there was no battle and Jackson marched away to later appear at McDowell, and we know what happened there on 8 May.]
No white flag of surrender, merely some imaginative reconnaissance.
