A pair of oxen may be called a “yoke of oxen” and when working in pairs, make a powerful team. Oxen can pull heavier loads, and for a longer period of time than horses but are also slower than their equine counterparts. However, their steady, dependable gate make oxen the preferred engine for hauling freight. One notable instance being the “Noble Train of Artillery,” where Colonel Henry Knox led an expedition to transport the heavy guns captured at Fort Ticonderoga to the Continental Army camps outside Boston during the winter of 1775-76. Teams of oxen drug the cumbersome cannons through miles of rough terrain in what has been called “one of the most stupendous feats of logistics” of the entire war.
