Camp at Tappan Septr. 28 1780
I am authorized, with your approbation, to take from the line of the army such & so many officers to serve in my department as I may find necessary, and as are willing to engage in the business. In consequence hereof I have agreed to appoint Major Cogswell waggon master for the main army, if your excellency should approve of it. I find it has been the usual practice in the German armies to appoint a field officer to that duty; and am led to think a similar appointment with us would be attended with advantages: but as it will be novel, I could wish, if your excellency should think proper, to announce Major Cogswell’s appointment in some such manner as is mentioned in the inclosed paper.
I shall be obliged to your excellency to inform the army of my appointment as quarter master general, and that of Henry Emanuel Lutterloh Esqr. whom I have appointed commissary of [forage] .

c.28 September 1780
It being the practice in foreign armies to take the principal waggon master from the line of the army; and as the service will probably be benefited by adopting that practice, the quarter master general, with the approbation of the commander in chief, has appointed Major Cogswell Waggon Master for the Main Army; & he is to be obeyed as such.
