The History of the Several Towns, Manors, and Patents of the County of Westchester (1881 revised edition, Vol. I)
The strictest discipline prevailed, and the army felt the fullest confidence in their commander and in themselves, and by these means became really formidable During the same winter, Gov. Tryon planned an expedition to Horseueck, for the purpose of destroying the Salt Works erected there, and marched with about two thousand men. Col. Burr received early information of their movements, and sent word to Gen. Putnam to hold the enemy at bay for a few hours; and he, Col. Burr, would be in their rear and be answerable for them.
THE, TOWN OF MOUNT PLEASANT.
By a messenger from him, Col. Burr was informed by that general that he had been obliged to retreat, and that the enemy were advancing into Connecticut. This information, which unfortunately was not correct, altered Col. Burr's route towards Mamaroneck, which enabled Tryon to get the start of him. Col. Burr then endeavored to intercept him in East Chester according to his first plan, and actually got within cannon shot of him. But Tryon ran too fast ; and in all haste, left most or all of his cattle and plunder behind him, and many stragglers who were picked up.
I will mention another enterprize which proved more successful, though equally hazardous. Soon after Tryon's retreat, Col. De Lancy, win commanded the British Refugees, in order to secure themselves against surprise, erected a block house on a rising ground below De Lancy's bridge. This, Col. Burr resolved to destroy. 1 was in that expedition, and recollect the circumstances. He procured a number of Grenades, also rolls of port fire and canteens filled with inflammable material, with contrivances to attach them to the side of the Block Douse. He set out with his troops early in the evening, and arrived within a mile of the block house by two o'clock in the morning.
