I take this as the first opportunity to acquaint you that on Tuesday last we got a severe flogging on Long Island. The enemy surrounded a large detachment of our army, took many, killed some, and the rest got off. Major Genl. Sullivan & Brigr Genl. Lord Sterling, Col. Clark and several other field officers are prisoners. Col. Johnson was killed. By the best act's we killed more of them than they did of us. But they took the most prisoners. We took twenty one, which I am a witness to, as they came through my Regt as I was in the woods for a covering party, and to prevent the enemy from flanking our right wing. We were prevented from getting even one shot at them by a large creek which we could not cross. I remained at the most extreme part of the right wing of our Army in a thick wood to prevent their crossing a creek, where our sentry's could hail and often fire at each other, until night before last when I received orders to call in my guard all, and march immediately with the utmost silence, which was soon done, and the whole army retreated into this city, without the loss of any lives, except 4 or 5, which were late yesterday morning and were shot in a boat, as they were coming off. We have also evacuated Governor's Island where we have lost some Cannon. What is to be our next manouver I can't tell but I hope it is to make a good stand somewhere. I am well convinced that for us to try to defend Long Island, New York, and the Jersey's against their land forces & shipping will require three armies as large as theirs, as they have the water carriage to place their men when & where they please. Many people I suppose will wonder at our leaving Long Island. But I would have them suspend their judgment for a while, as they know not our situation or the enemies! The shipping lay now close by the city, and can in half an hour be abreast of it with the tide. I expect we [shall] soon have a cannonade from our own battery on Long Island, (Fort Sterling) which I have the mortification to think I helped build myself, in cold tedious weather! They fired smartly from it yesterday at our boats passing from Governor's Island....

Country Seat near Turtle Bay,
Septr 7th 1776.

Our Army is now in three grand Divisions. One at the City, which is our right wing, commanded by Genl. Putnam, one at and above Kings Bridge, commanded by Genl Heath, and one at and about Harlem, commanded by Genl Spencer, which is the Division that I belong to, and is called the Center Division. I have three Regts of militia in my Brigade and they give me much fatigue & trouble. Col's. Cook, Pettibone, & Talcott are the commanders. We are encouraged by 1500 Troops which have come in from Maryland. I am sorry to say it but it is a truth, I do not believe that we have got in all our Army as many men as the enemy. I have heard that it has been said in the country that we should not have left Long Island, but salied out and drove the enemy off. We never were more than one to three, on the Island, neither was it so prudent to abandon other posts for that, as the shipping could & have since come up the East River and then our communication was gone, and the Army with it. We are now so as one part can get to the other, without water carriage, & think if we will only stand by each other, and not run home like cowards, with God's blessing, we may keep them off, which is a victory of itself! I have taken unwearied pains with the Militia, and I am afraid it is too much fatigue for me, as my cough is a little increased. But I hope it is only for a short time.... My expenses has been so large that my money falls a little short. I was obliged to entirely support the sick of my Regt for some time, but I suppose you have none to spare. I shall make out, but not so well as I could wish....

In the field at the lines on Harlam Heights,
18th Sept 1776.

Since I wrote last we have had different scenes to go through. I lay with my brigade a little below Turtle Bay where we hove up lines for more than one mile in length. Gen'l Wadsworth managed the lines on the right and I on the left. We lay in the lines Friday and Saturday nights. Sunday morning at break of day, five ships weighed anchor and fell in close within a musket shot of our lines quite to the left of me. I then moved my brigade abreast of them. They lay very quiet until 10 o'clock and by that time they had about 80 of their boats from under Long Island shore full with men which contained about five or six thousand and four transports full ready to come in the second boats. They very suddenly began as heavy a canonade perhaps as ever was from no more ships, as they had nothing to molest them, but to fire on us at their pleasure, from their tops and everywhere—their boats got under cover of the smoke of the shipping and then struck to the left of my lines in order to cut me of from a retreat. My left wing gave way which was formed of the militia. I lay myself on the right wing waiting for the boats until Capt Prentice came to me and told me, if I meant to save myself to leave the lines for that was the orders on the left and that they had left the lines. I then told my men to make the best of their way as I found I had but about ten left with me. They soon moved out and I then made the best of my way out. We then had a mile to retreat through as hot a fire as could well be made but they mostly overshot us. The brigade was then in such a scattered poster that I could not collect them and I found the whole army on a retreat. The regulars came up in the rear and gave me several platoons at a time when I had none of my men with me and I was so beat out that they would have had me a prisoner had not I found an officer that was obliged to leave his horse because he could not get him over a fence so as to get out of their way. I found myself gone if I could not ride. I went over the fence and got the horse over whilst they were firing, mounted him and rode off. We halted here at night and on Monday the enemy came on and we gave them a good drubbing. I have not time to give you the particulars of any part of our action. I have lost my major, a prisoner,—One sargeant or more killed and four wounded,—have missing out of my brigade which sustained the whole fire but 8 or 9 as yet. I hope God will be on our side at last. It is memoriable that I have lost no more and God be praised for it. Our lines are now good and if they dare come on without their shipping I hope we shall give them a drubbing. In the utmost haste

From your faithful husband

I this moment received yours of the 8th inst, but have not got my horse yet. he is left on the road. My love to the children.

White Plains 31st Octr, 1776.

On Monday the enemy advanced to attack us at this place. I was ordered out with my regiment with three others to meet and endeavor to retard their march. We moved on and at about twelve were attacked by their advanced guard. We drove them back but soon after the main body came on and we stood them until they got on our flank and I ordered a retreat. We had a most severe fire to retreat under, ten men to our one, but we came off in good order and very surely fired on our retreat all the way. I lost three dead and five wounded. They cut my regiment off from our main body and got ahead of me but I took advantage of a wood and got clear of them. My regiment has the honour of behaving most nobly. They are now near neighbors, our lines are about half a mile.
