 At 9 : 15 the Montagu engaged the Diligente , which struck after her <unk> was shot away . Around 11 : 00 pm San Eugenio surrendered after having all of her masts shot away by HMS Cumberland , but the difficult seas made it impossible to board a prize crew until morning . That duel was passed by HMS Culloden and Prince George , which engaged San Julián and compelled her to surrender around 1 : 00 am . The last ship to surrender was Monarca . She nearly escaped , shooting away HMS Alcide 's topmast , but was engaged in a running battle with the frigate HMS Apollo . Apollo managed to keep up the unequal engagement until about the time that Rodney 's flagship Sandwich came upon the scene around 2 : 00 am . Sandwich fired a broadside , unaware that Monarca had already hauled down her flag .
