HMS Thistle (1899)
HMS ''Thistle'' was a ''Bramble''-class gunboat of the Royal Navy, launched in 1899 and broken up in 1926. She is notable for being the last classic Victorian gunboat, and the last British warship to retain a practical sailing rig.
==Design==
(詳細はBritish Empire in the era of gunboat diplomacy.
In most respects, she resembled a scaled-down protected cruiser, a steel warship with a modern design and up-to-date armament, and very comfortable quarters for her crew. However, in order to navigate on uncharted coasts and tropical rivers, she was given a very compact shallow-draught hull, and this meant she only had a very limited coal supply. In addition, low technology was used to minimize construction cost and logistical requirements. As a result, the ''Thistle'' was given a two-masted sailing rig as a supplementary means of propulsion, along with a number of other anachronistic features such as a manual capstan to raise the anchor, and candles rather than light bulbs.
Policy changes shortly after the ''Thistle'''s launch meant that no further gunboats would be built for the Royal Navy, and the use of sail propulsion was strongly discouraged. Nonetheless, problems with using ''Thistle'''s engines for long-range cruising would prompt the restoration of her sailing rig in 1919, while her usefulness on colonial stations meant that she was refitted to maintain her capabilities in the 1920s, acquiring an anti-aircraft armament.
