Philadelphia and Harrisburg, 1852–1949. description ends , 1st ser., 6:708), and Arnold to Henry Laurens, 19 Aug. (DNA:PCC, item 162). Arnold was referring to “An Act to regulate the Militia of the Common-Wealth of Pennsylvania,” 17 March 1777, which authorized the executive council to call up the militia “in case of invasion or rebellion within this State, or in case the assistance of the militia of this State shall be requested by Congress to assist the Continental Army in this or any of the adjoining States” (Pa. Laws, 25).
2. Congress read Arnold’s letter on 20 Aug. and directed the Board of War “to report their opinion on the necessity of an additional number of troops to the corps of invalids, for the purpose of guards in the city of Philadelphia; and if an additional number is … necessary, how many and for what purposes.” The board’s report of 28 Aug. was considered on 3 Sept., and Congress resolved to request that the Pennsylvania council call up three hundred militia to serve as guards in Philadelphia ( JCC description begins Worthington Chauncey Ford et al., eds. Journals of the Continental Congress, 1774-1789. 34 vols. Washington, D.C., 1904–37. description ends , 11:816, 12:865). The council responded on 4 Sept. by calling militia into service ( Pa. Col.
