Federal cavalry camp.This photograph of an Illinois regiment's Camp at Baton Rouge was taken in 1863, just before the Port Hudson campaign upon which Grierson and his men accompanied General Banks. The troopers have found fairly comfortable quarters. The smoke rising from their camp-fires lends a peaceful touch to the scene. A cavalry Camp occupied more space than an infantry camp. The horses are tethered in long lines between the tents, about the width of a street-way. They are plainly visible in this photograph, tethered in this fashion, a few of them grazing about the plain. In the foreground by the officers' quarters, a charger stands saddled, ready for his master. This is an excellent illustration of a Camp laid out according to Federal army regulations.
