Twice, after her repairs had been completed and as she was about to get underway, the frigate was kept in port by lightning-splintered mainmasts. Meanwhile, more and more crewmen were lost to sickness, desertion, and the lure of higher pay on merchant vessels. Recruiting was stimulated by the issuing of bounties, and
Randolph was finally readied for sea - this time with her masts protected by
lightning rods. She departed Charleston on 16 August and was positioned by Biddle at the mouth of the harbor awaiting favorable winds to put to sea. Two days later, a party from the frigate boarded a departing merchantman,
Fair American, and took back into its service a pair of deserters among the ship's crew. Inshore winds kept
Randolph trapped until the breeze shifted on 1 September, wafting the frigate across
Charleston Bar. At dusk, on the 3rd, a lookout spotted five vessels: two merchant ships, two
brigs, and a
sloop. After a nightlong chase, she caught up with her quarry the next morning and took four prizes. The first, a 20-gun privateer,
True Briton, was laden with
rum for the British troops at New York;
Severn, the second prize, had been recaptured by
True Briton from a North Carolina privateer while sailing from
Jamaica to
London with a cargo of sugar, rum, ginger, and
logwood. The two brigs,
Charming Peggy, a French privateer on escort duty, and
L’Assomption, laden with salt, had also been captured by
True Briton while plying their way from
Martinique to Charleston.
Randolph and her prizes reached Charleston on the morning of 6 September. While the frigate was in port having her hull scraped, the president of
South Carolina's General Assembly,
John Rutledge, suggested to Biddle that
Randolph should join forces with the
State Navy and break the British naval blockade of Charleston. Biddle accepted temporary command of the fleet, which, besides
Randolph, included
General Moultrie,
Notre Dame, the converted
Fair American, and
Polly. The American ships sailed on 14 February 1778 but encountered no British warships. Biddle then ordered his captains to proceed to the West Indies, hoping to intercept British merchantmen. After two days, they captured (and were subsequently forced to burn) a dismasted and unsalvageable New England merchantman which had been captured by a British privateer while headed for
St. Augustine, Florida. Thereafter, game was scarce. They encountered only neutral ships until
Polly took a small
schooner on 4 March bound from New York to
Grenada. Biddle had the ship repurposed as a
tender. == Loss ==
