American Revolutionary War In 1778, Curtis returned to Britain in
Eagle, but refused to carry out an order to sail the ship to the Far East, a refusal which earned the enmity of
Lord Sandwich. In December of the same year he was married to Jane Sarah Brady. As punishment for his disobedience Curtis was unemployed for the next two years, before he secured the new frigate
HMS Brilliant for service in the
Mediterranean in 1780. Ordered to
Gibraltar,
Brilliant was attacked by a superior Spanish squadron close to the fortress and was forced to escape to British-held
Menorca. Curtis's first lieutenant Colin Campbell complained extensively about his captain's refusal to leave port while enemy shipping passed by the harbour, but Curtis was waiting for a 25-ship relief convoy which he met and safely convoyed into Gibraltar, bringing supplies to the defenders of the
Great Siege of Gibraltar then in progress. He came under attack however from Lieutenant Campbell, who published a pamphlet accusing him of indecision and a lack of nerve during his time in
Brilliant.
Brilliant was paid off in 1784, although Curtis remained in employment during the peace, commanding
HMS Ganges as guardship at Portsmouth. In 1787 he was placed on half-pay, although it has been speculated that during this period he conducted a secret mission to Scandinavia to ensure British supplies on naval materials from the region in the event of war. , 1795 In the closing stages of the battle, the aged Howe retired to his cabin and Curtis was given responsibility for the flagship and consequently the fleet over the next day. Although Howe had ultimate responsibility for the despatch, many blamed Curtis for this slight and he was rumoured to have taken the decision to abandon pursuit and subsequently penned the report himself in Howe's name. for his role in the action, another captain,
Anthony Molloy, faced a court martial and national disgrace for what was considered to be his failure to engage the enemy during the battle. Curtis stood as prosecutor in the case, and Molloy was subsequently dismissed from his ship and effectively from the service as the result of Curtis's prosecution.
Cuthbert Collingwood, one of the captains overlooked by the despatch, subsequently described Curtis as "an artful, sneeking creature, whose fawning insinuating manners creeps into the confidence of whoever he attacks and whose rapacity wou'd grasp all honours and all profits that come within his view". He was also in overall command of the naval operations which succeeded in destroying or driving off much of the French force sent to support the
Irish Rebellion of 1798 culminating in the
Battle of Tory Island, at which he was not present. In 1799, he retired ashore.
Staff service Curtis's remaining career was based at a series of shore stations, initially as commander-in-chief
Cape of Good Hope Station at
Cape Town between 1800 and 1803, which he reportedly hated. In 1804 he was promoted to full admiral, and subsequently employed in Britain from 1805 to 1807 as part of the "Commission for revising the civil affairs of His Majesty's navy". This latter role was an important position and Curtis performed well, introducing many beneficial reforms to the service. In 1810, he performed his last significant duty, when he presided over the highly controversial court martial examining the conduct of
Lord Gambier at the
Battle of Basque Roads. At the battle, Gambier had failed to support Captain
Lord Cochrane and missed an opportunity to destroy the French Brest Fleet. Infuriated, Cochrane attempted to block the proposed vote of thanks awarded to Gambier for the reduced victory from
Parliament. Gambier responded by demanding a court martial to pass judgement on his actions. Gambier and Curtis had fought together at the Glorious First of June and had been friends for many years, and Curtis could be counted on by those in authority to "show strong partiality in favour of the accused." Under instructions from the Admiralty, Curtis and the other officers judging the case found in Gambier's favour and the trial inevitably ended with the court pronouncing that Gambier's behaviour "was marked by zeal, judgement, ability, and an anxious attention to the welfare of his majesty's service". Curtis retired after the trial and died six years later after a peaceful retirement on 14 November 1816 at his residence Gatscombe House, followed a year later by his wife. The Curtis family also owned a farm in
Catherington, Hampshire, the buildings of which was uncovered during land clearance in 2021. On his death, his son,
Lucius Curtis, inherited the baronetcy. Lucius was an experienced
post captain who had lost his ship at the
Battle of Grand Port but was exonerated at the subsequent court martial and eventually became an
admiral of the fleet. Roger Curtis's highly controversial career was noted for a number of prominent public disputes, that resulted in bitterness between Curtis and several of his fellow officers. He was however, brave and resourceful; his actions at Gibraltar even prompted the naming of the
Curtis Group, an archipelago of small islands in the
Bass Strait between
Australia and
Tasmania: The islands were apparently given the name because of their physical similarity to Gibraltar. ==Coat of arms==
