The Autobiography of Benjamin Franklin

Loudoun, instead of defending the colonies with his great army, left them totally expos'd while he paraded idly at Halifax, by which means Fort George was lost, besides, he derang'd all our mercantile operations, and distress'd our trade, by a long embargo on the exportation of provisions, on pretence of keeping supplies from being obtain'd by the enemy, but in reality for beating down their price in favor of the contractors, in whose profits, it was said, perhaps from suspicion only, he had a share.†

And, when at length the embargo was taken off, by neglecting to send notice of it to Charlestown, the Carolina fleet was detain'd near three months longer, whereby their bottoms were so much damaged by the worm that a great part of them foundered in their passage home.†
