Camp, Oct. 14. 1780.
I beg leave to solicit your Excellency for the liberty of resigning my Commission in the Army. This I am urged to solely by the calls of my domestic affairs, and not from any inconveniencies which have occurred in the course of this War. My zeal for the cause remains the same, & will continue to be seconded by my aid to the utmost of my abilities: And it is with regret I shall retire from an Army in which I have had the honour of serving since its commencement, and for which my affection will be lasting; especially while our present commander in Chief continues to preside. I am with every sentiment of respect & esteem, your Excellency’s most obedt hume Servt
Silas Burbank, Capt.
12. Mass. regiment, and 4. Brigade.
