I am here on the Tryal of Genl. Arnold, in which we have made great progress, and shall finish in a few days, after which I shall immediately proceed to Fishkiln, unless some other Business in Court Martial way should start up, which I flatter myself will not be the case. The first Division of the British Fleet sailed yesterday, whether with Troops for Charles Town, or Bound for Europe without Troops, is matter of speculation, but the latter opinion prevails here. On which side, however, truth may lie as to this question, certain it is that a very large Embarkation has taken place, and that the Vessels are fallen down to the Hook will probably sail for Devoted Charles Town in a few days. Indeed their Destination is so well ascertained as to be out of Doubt, in consequence of which the Brigades of Virginia and North Carolina are ordered Rapidly to march for that place; but, alas! I fear their aid is too feeble to save it, even supposing they should arrive in time, which it is almost impossible they should. It is, however, all that the General can do in the present situation of affairs. It is said and believed here that Sir H. Clinton is to go in person, having vowed to Reduce the three Southern States at least to due allegiance. Sorry I am to add that as to conquest his success is too probable, but as to allegiance he cannot succeed. I have no other news to write, nor have I time to write it if I had. My affectionate comp'ts to Mrs. Maylon. I have inquired after her friends and hear they are all well. God bless you, Dear Sir.
