On this date 250 years ago in Philadelphia, the Continental Congress

Resolved, That no produce of the United Colonies be exported, (except from colony to colony, under the direction of the Committees of Inspection and Observation, and except from one part to another of the same colony) before the first day of March next, without the permission or order of this Congress: provided, that nothing herein contained shall be construed to vacate the resolutions of Congress for the importation of arms, ammunition, &c.
The Congress had previously banned imports from Great Britain but now determined that exports needed to be approved by Congress to make sure that they would not undermine the war effort.

On that same day Congressman Samuel Ward of Rhode Island wrote to his wife Deborah

We have nothing to expect but War and I think We are in a Way to carry it on with the greatest Success. Gentlemen who a few months since could not bear the Idea of War now cheerfully concur with us in the most spirited Measures. In one Word my Dear We are determined to spare neither Men nor Money; May God of his infinite Goodness direct & Prosper all our Measures & in his own due Time restore Peace, Liberty & Safety to this Continent.

. . .

Two Ships have arrived from London. They bring over amongst other Things a Proclamation dated 23rd August for suppressing Rebellion & Treason in the Colonies. We are all declared to be Rebels in effect though not in express Terms, this has a most happy Effect here for those who hoped for Redress from our Petitions now give them up & heartily join with us in carrying on the War vigorously
