Head Quarters [Cambridge] 30th October 1775
Sir
His Excellency General Washington directs me to acquaint that, it is necessary for the publick Service that you be at Cambridge Wednesday Night [November 1] as The Vessells that were expected at Portsmouth, are said to be return'd to Boston. I apprehend they have laid aside their design upon portsmouth for the present. The General is now confident, from your Vigilance, that the Enemy can only meet with disgrace, should they dare to make their Appearance before that Town.
