Some time in the month of September, during my absence from my command, six of my men who had been captured by your forces, were hung and shot in the streets of Front Royal, by order and in the immediate presence of Brigadier-General Custer. Since then another (captured by a Colonel Powell on a plundering expedition into Rappahannock) shared a similar fate. A label affixed to the coat of one of the murdered men declared "that this would be the fate of Mosby and all his men."
Since the murder of my men, not less than seven hundred prisoners, including many officers of high rank, captured from your army by this command have been forwarded to Richmond; but the execution of my purpose of retaliation was deferred, in order, as far as possible, to confine its operation to the men of Custer and Powell. Accordingly, on the 6th instant, seven of your men were, by my order, executed on the Valley Pike - your highway of travel.
Hereafter, any prisoners falling into my hands will be treated with the kindness due to their condition, unless some new act of barbarity shall compel me, reluctantly, to adopt a line of policy repugnant to humanity.
