ELIZABETHTOWN-NEWARK-PASSAIC RAID. 12-21 September 1777. General Henry Clinton sent two thousand British, German, and Loyalist troops into New Jersey at three different places on 12 September to conduct foraging operations. Brigadier John Campbell landed at Elizabethtown and swept north; Major General John Vaughan landed at Fort Lee and headed west toward Slotterdam; and a much smaller element came ashore below Tappan and swept south. On 13 September they linked up and engaged in day-long skirmishing along the Passaic River. American forces from the Hudson Highlands came south in reaction under the command of Brigadier General Alexander McDougall, and in a series of small clashes between patrols they established that Clinton was merely on a raid. The British returned to New York on 21 September with only a small amount of livestock.
