Attacks were made the 22nd inst. on Forts Mifflin and Redbank, in both of which the enemy were repulsed. A Battery on Province Island and two upon the bank opposite to Fort Mifflin, thrown up to reclaim the great Marsh below Province Island, were opened upon the Fort and were supported by six ships warped through the Chevaux de frise at Billingsfort. Our Gallies and armed vessels in the River assisted the Fort, and in conjunction, they kept up so effectual a cannonade upon the ships, as to disable a 64 Gun ship and sloop of war, a small Frigate, and the enemy set them on fire before they quitted. One of the four, that retired, was the Roe-buck greatly damaged. Baron Donop with 1200 men attacked Red bank, and after a short cannonade, marched up with fixed bayonets in two columns. They passed the avetti, entered the ditch, some passed the picket, but were so warmly received, they fell back and fled, leaving Donop, his Brigade Maj., a Capt. Lieut. and upwards of seventy men wounded and prisoners—one Lieut.-Colonel, three Capts, four Lieutenants, and nearly seventy killed, near three hundred muskets and a considerable quantity of cartridge boxes &c, taken. We lost one Captain, three Serg'ts, one fife, four privates killed. One Ensign, five Serg'ts, twenty three privates, wounded. The loss in our vessels and Fort Mifflin very inconsiderable.
