"None of them seem to have done much professional work in the battle but they assisted in posting troops and batteries, a duty for which they were well qualified through knowledge of the tactical value of ground."

"Williamson and Harris, who had been there since May, had laid out and built the defenses of Manassas Junction chiefly with slave labour and, presumeably, had also supervised those which were built by Bonham's and Jones' brigades along Bull Run."
