On this day 250 years ago in Philadelphia, the Continental Congress recorded in its Journal:

Information being given to Congress that some prisoners in the gaol of this city have meditated an escape, and are near carrying their plan into execution:

Resolved, That the gaoler be directed to confine John Connolly, J. Smith, and [Moses] Kirkland, in separate apartments, and suffer no person to converse with any of them, without special orders of Congress.

Resolved, That the sheriff of the city and county of Philadelphia be directed, by Mr. [Thomas] M’Kean, to call to his assistance a guard of fifty men from the barracks of this city for the defence of the gaol; and that the sheriff be farther directed to keep secret any intimation given him of a design to rescue his prisoners, and employ every means to discover and apprehend those concerned in such design.

Also on that day in Philadelphia, Congressman Oliver Wolcott of Connecticut wrote to Connecticut lawyer Samuel Lyman:

G. Britain will proceed doubtless upon their usual Governmental Maxims–Violence and Corruption–but neither I hope will succeed against America….Some few Americans may wish to support a Monarchy which is lavish in its Bounties, hoping to Share in the oppressions of Power.  Some may be timid and fearful of entering upon untried Scenes and others who have supported the Distinctions of an Aristocracy may fear the Prevalency of a Republican Spirit.  But God has evidently Appeared to Vindicate the Rights of this People… The Expulsion of the Troops from Boston is a great Event, it has brought a Disgrace on the British Arms which they had not to so such a Degree suffered for a long Time.

Wolcott would sign the Declaration of Independence and continue in public service for the rest of the War. Lyman would be elected to Congress from Massachusetts after the War.
