A good deal of trouble arose from what was called the Neutral Ground, extending some 30 miles above the Island of New York, and not included in the lines of either army. It was a fertile and populous country, but much infested by bands of plunderers, called cow-boys and skinners. The cow-boys lived within the British lines, and bought, or stole, cattle for the use of the troops. The rendezvous of the skinners was within the American lines. They professed to be great patriots, making it their ostensible business to plunder those who refused to take the oath of allegiance to the State of New York. But they were ready in fact to plunder any one, and the cattle they thus obtained were often sold to the cow-boys in exchange for dry goods from New York. It was when traversing this neutral ground, that the unfortunate Major André was captured. By the way, the General in his morning's ride passed the house where André was to dine the evening before he should start on his ill- fated journey. It was an old Dutch house which remained standing until 1850, near the present intersection of 2nd Avenue and 34th Street; and was occupied during the British occupation, as an officer's quarter, by Colonel Williams of the 80th Regiment. In continuing his ride, the General went to Greenwich, a village situated at that time a mile and a half out of the city, but now in the very heart of it, where the German troops in English pay were stationed. Of all the mistakes made by England in that war—and they were many—the hiring of mercenaries to fight the Americans was perhaps the greatest. It irritated many loyal men into rebellion, and gave a union and cohesion to the disloyal, such as they never otherwise would have gained. Nor were the mercenaries very valuable as soldiers; they were discontented and quarrelsome; and to their want of vigilance was the irreparable disaster of Trenton wholly due. Even to this day, the Americans talk most bitterly of their being hired by the English to shoot down their own flesh and blood; and there can be no doubt that more soreness was due to this circumstance, than to any other connected with the war. Apart, however, from the general question, there was no Commanding officer whose management of the foreign troops displayed so much tact, as General Pattison. Whether it were on duty, or on such occasions as the celebrated ball given by him on the King's Birthday in 1780, which he opened with the wife of the German Baron who commanded at Greenwich, his courtesy and tact were always exerted to cement differences, or allay grievances.
