Orde joined the Royal Navy in 1766 and was promoted to lieutenant in 1774. He served throughout the American revolutionary war, and was promoted to post captain on 19 May 1778, making him senior to Nelson by less than a month. Orde served as Governor of Dominica from 1783 until 1793 and on 9 August 1790 was made a baronet. He returned to naval service and was promoted rear admiral 1795.
Relationships with Jervis and Nelson
In early 1798, Orde was appointed to the Mediterranean fleet as third in command under John Jervis, 1st Earl of St Vincent. In May 1798, acting on his own initiative but with the support of Lord Spencer, the First Lord of the Admiralty, St Vincent gave command of a special squadron to Nelson. As Nelson's senior, Orde felt he had been unfairly passed over and complained to St Vincent who, annoyed at his subordinate's questioning of his orders, relieved Orde and ordered him home. Orde requested that he be court-martialled in order that he might have the opportunity to clear his name. The Board refused.The Naval Chronicle Vol. 11, p. 194 Orde then requested that St Vincent be brought before a court-martial. Again, the Board refused. The Board did go so far as to censure Jervis for not having supported his subordinates. Orde, unhappy with the outcome, challenged the earl to a duel. The challenge became public knowledge and the king ordered Jervis to decline. Before the challenge was formally declined, however, Orde wrote to the Board to inform them that he had withdrawn it. Neither side came out of the situation well. Had Nelson not won such an extraordinary victory at the Battle of the Nile, Jervis may have faced a court martial for not having supported Orde. Unfortunately for Orde, Nelson's victory was so complete that any criticism of Nelson or Jervis fell on deaf ears. Nelson naturally took Jervis's side and regarded Orde as a personal enemy but Orde maintained that it was the principle of the appointment he objected to, not the person who had been chosen. Things became worse for Orde when St Vincent was appointed First Lord of the Admiralty. St Vincent now controlled appointments and Orde found himself left ashore. St Vincent left the Admiralty in 1804 and Orde was offered command of a newly formed squadron off Cadiz. This further angered Nelson who saw it as a deliberate diminution of his authority.
The Spanish squadron
Orde's squadron of six ships of the line were stationed off Cadiz when Villenueve arrived with the Toulon fleet in April 1805. Orde's ships, which were busy revictualling at the time, cast off their store ships and hastily formed line of battle. Villenueve however, with his eleven ships of the line and six frigates, made no attempt to engage the squadron. Greatly outnumbered, Orde retired, an act that earned him condemnation from some, Nelson included. Villenueve gathered the ships that were ready to sail and put to sea again. Orde believed they were bound for the English Channel but in fact Villenueve was on his way to the West Indies. Orde therefore took his squadron north to rendezvous with the Channel Fleet. Although technically correct, Orde's behaviour was not in accordance with the country's mood at the time and he was ordered to strike his flag. He never served at sea again. In 1807, Orde became the member of parliament for Yarmouth, Isle of Wight and served in that capacity until his death on 19 February 1824. Orde never appeared to reciprocate Nelson's animosity and was one of the pall-bearers at Nelson's funeral in January 1806.
Family
Sir John Orde was married twice, to Margaret Emma Stephens in 1781, who died in 1790; and Jane Frere in 1793, with whom he had two children: John Powlett Orde, born 9 June 1803 and Anna Maria Fenn Orde, born 1806.
