What happened
The crew had objected to the fight, and the record gives their reason.
The plan was to enter Belfast Lough a second time and attack the Drake "in plain day." The crew thought the project "by no means right, because it involved honor more than self-interest, their only motive." Spurred on by the ship's two naval lieutenants, they took the occasion to mutiny.
The mutiny was not talked down. Lieutenant Meijer happened on the plan in time and warned Captain John Paul Jones, "who, when Master Cullam rushed him as a signal for the mutiny to begin, put a pistol to his head and quashed the plot."
What changed the crew's minds was not the pistol. It was a small success, and the record is specific about it.
A strange vessel had been sighted entering the lough close to Kilroot Point, and the Drake's captain, uncertain of her identity, ordered a boat sent to investigate. Jones "kept his now-quieted crew below decks, his guns masked, and the sloop's stern toward the approaching boat."
The gig drew alongside, the British lieutenant in charge came on board, and "he was immediately informed that he and his crew were now prisoners."
"This trifling success had such an exhilarating effect on my crew," Jones later wrote, "that they no longer objected to giving battle."
Only then, "taking the boat in tow," did Jones decide "to draw the Drake into the channel where he would have more room to maneuver." The Drake worked slowly out of Carrickfergus Bay against an unfavorable wind and flood tide, and after she weathered Kilroot Point, Jones allowed her to approach within hailing distance.
The Ranger placed herself directly across the Drake's bow and fired a broadside of grape that swept along the enemy's deck. "The action was warm, close, and obstinate," Jones reported; "it lasted an hour and four minutes."
Then the enemy called for quarters, her captain and four others dead, her lieutenant and nineteen others wounded, and her rigging cut to pieces.
The Ranger's dead were Samuel Wallingford, who received a musket ball in the head, and two seamen. Five were wounded.
The sentence this entry exists for comes straight after the casualty list. "Sergeant of Marines John Ricker was immediately given charge of the ship's Marine detachment until a replacement could be found."
Charles R. Smith's official history tells it a second time, in an appendix sketch of the man who filled Wallingford's vacancy. Smith's preface credits the officer sketches to Richard A. Long, and Long's wording is plainer: following the engagement and the death of Wallingford, "sergeant of Marines John Ricker took temporary command of Ranger's Marines."
The day after the battle, 25 April, both crews repaired damage. Before noon a large brigantine from Whitehaven, bound for Norway, sailed so close to the Drake that Jones was obliged to take her. That evening a solemn service was held on deck and Wallingford's body was committed to the deep.
The Ranger and her prize reached Brest on 8 May. On 26 May the Continental Navy Agent at Nantes, Jonathan Williams, wrote to Jones recommending William Morris to fill the vacancy left by Wallingford's death, and enclosed a letter from Morris.
Smith's chapter quotes Morris himself: "my intentions are intirely to Serve my Country and wish to enter into the Servise with no other View." Long's sketch quotes the enclosed letter in fragments, with Morris expressing his appreciation that Jones considered him "worthy of being Lieut, of the Merrines" and saying he would "proceed to Breast as sone as posoble."
Smith's chapter has Morris appointed lieutenant of Marines "upon his arrival at Brest in June." Long's sketch has him joining the Ranger at Brest in July 1778. Neither gives a day.
The chronology of the Corps places the action between the Ranger and the Drake "off the coast of England," where Smith has the Drake coming out of Carrickfergus Bay. For 25 April it records the capture of the British brig Patience; Smith has an unnamed brigantine from Whitehaven taken that day, and neither source says the two are the same vessel. This entry follows Smith, who narrates the action at length.
