ABSTRACT
IN THE FEBRUARY, 1916, ISSUE OF THIS JOURNAL, the author described a formidable war machine, termed the “Trench Tractor.” This machine was conceived primarily to force a breach in an existing, well defended trench. Once across the trench, the infantry could force its way thru and then perhaps attack another portion of the trench from the rear, conditions being favorable. As will be remembered, the Trench Tractor was no mere bagatelle, it measuring 140 feet from wheel to wheel, while the tractor wheels themselves were over 40 feet high.
