From Diary of the American Revolution, Vol II. Compiled by Frank Moore and published in 1859.
October 2.—Arnold’s conduct since he went to New York, is a greater proof of his villany (if greater villany is possible) than his late treason. At his arrival with the British, says a gentleman in the American army, he had upwards of fifty of our warmest friends in New York taken up, and put into dungeons and other places of confinement. But there is a Providence attending the unhappy friends to their country, that puts it out of his power to injure them, other than imprisonment. Such was the precipitate flight he made, to save his neck from the halter, that he had no time to move off a single paper, or any other matter which can be a testimony against those he would otherwise ruin in person and estate.1
