How dare anyone question General McCaffrey? He is a war hero, and war heroes are above any possible reproach.
Benedict Arnold V (January 14 1741 [O.S. January 3, 1740] – June 14, 1801) was a general during the American Revolutionary War . . . Arnold is considered by many to be the best general and most accomplished leader in the Continental Army. Without Arnold's earlier contributions to their cause, the American Revolution might well have been lost. . . Arnold distinguished himself early in the war through acts of cunning and bravery. His many successful campaigns included the Capture of Fort Ticonderoga (1775), victory at the Battle of Valcour Island on Lake Champlain in 1776, the battles of Danbury and Ridgefield in Connecticut (after which he was promoted to Major General) and the Battle of Saratoga in 1777.
