They appear to have been billeted on private householders or lodged in taverns, and were doubtless, in the one case, a nuisance to their hosts, while, in the other, they were put in the way of evil companions. Viewed at the moment it was effected, and not judged of by its results, this collection of the guards into one camp appears to have been a prudent measure—one that even a wise and honest minister might have devised or sanctioned.
