The list below includes significant Royal Naval Hospitals established in the 18th-20th centuries; in addition numerous smaller facilities (often classed as Sick Quarters) were set up, where and when needed (especially in times of war).
Individual surgeons had been appointed to naval vessels since Tudor times;[5] the Company of Barber-Surgeons was expected to provide them in suitable numbers whenever the fleet was due to set sail.
The following year, commissioners of sick and wounded were appointed to supervise the distribution of funds, the provision of surgeons and medicines, the deployment of patients (and, where possible, their eventual return to service).
An early experiment was the prefabricated hospital set up in Jamaica by Admiral John Benbow in 1701, for which the Sick and Hurt Commissioners provided a salaried surgeon and other staff.
[12] During the War of Jenkins' Ear, however, the system was overwhelmed by large numbers of returning sick and injured (over 15,000 in the 13 months from July 1739 to August 1740).
[10] The following year a proposal was put forward to the Admiralty for the establishment of three hospitals, to be owned, built and run by the Royal Navy, in the vicinity of the principal home ports.
Gibraltar served the needs of the fleet in the Mediterranean at this time (Minorca having been ceded to Spain); while, further afield, Royal Naval Hospitals had been established in various locations including India, North America and the Caribbean.
[14] The main overseas Royal Naval Hospitals at this time were on Malta, Gibraltar, Bermuda, the Cape of Good Hope and Hong Kong.
During the Second World War there was concern about the vulnerability of the older hospitals (which were prominent buildings close to naval dockyards) to aerial bombardment.
[16] Malta was also seen as vulnerable to attack, so an auxiliary hospital was opened in a wing of Victoria College, Alexandria to serve the needs of the Mediterranean Fleet.
[16] Further east, RNH Hong Kong was destroyed by bombing in 1941, leaving auxiliary hospitals in Ceylon, South Africa and Oceania to take up the strain.
These numbers were subsequently scaled down, as efforts were made to reduce overcrowding (e.g. by the end of the 19th century Plymouth had fourteen beds to a ward, rather than twenty).
To counter this, the decision was taken to remove administrative oversight from the medical staff and to vest it in a trio or quartet of serving naval officers, who were given accommodation on site: the Governor (usually a post-captain) and two or three Lieutenants.
