"It may well be imagined that the privilege of passing the lines and traveling all over the country, enjoyed by the 75th, was calculated to arouse more or less envy.

Such was the case, and many soldiers of other organizations pass them selves off as 75ers, and under this pretense got beyond the pickets, committing shameful thefts and outrages in the surrounding country.

Thus in time complaints of ill-treatment reached headquarters, and the regiment, undeservedly, received a reprimand... On these occasions, as when capturing horses and saddles, the soldiers pitied those whom they were robbing, satisfying their consciences with the thought that those who had brought on this distressing war were the ones who were to blame for its fruits."
