Morristown May 9th 1780
I received your letter of yesterday. You have my permission to endeavour to ascertain the strength of the party at Bull’s ferry and to make an attempt upon it, if you think there is sufficient probability of success. You will no doubt at the same time be upon your own guard lest this party should meditate something against you. I am, &c. Your most Obedient and humble servant.
