New-Orleans July 7th. 1807.
Captain Cammack of the Marine Corps being order’ed to the City of Washington, I cannot avoid testifying to you my entire approbation of his Conduct while on this Station, and recommending him to your notice as an officer of merit and Talents;—He has for some time commanded the Marines at New-Orleans, & while his own Department has been uniformly correct, the most exact discipline has been observed by the Corps under his Command.
You will excuse the liberty I take in addressing you this Letter;—my only object is to render justice to merit, and to acquaint you of the zeal, fidelity and Ability, with which Captain Cammack has in this Station discharged his duty.
I am DrSir, With great respect & Esteem! Your hble servt
