Haversacks
A small square bag, made of canvas and called the haversack was suspended from the left shoulder and was used to carry all sorts of personal gear including food and spare clothing. The Highlanders also carried a backpack, which was centered high on the back, Indian-style, with underarm straps, which was used to carry food, extra clothing, and extra ammo.
