Cruizer-class Sloop

The ''Cruizer'' class was a class of six 17-gun wooden screw sloops built for the Royal Navy between 1852 and 1856.

Design

The wooden sloops of the ''Cruizer'' class were designed under the direction of Lord John Hay, and after his "Committee of Reference" was disbanded, their construction was supervised by the new Surveyor of the Navy, Sir Baldwin Walker. A pair of ships named ''Cracker'' and ''Hornet'' had been ordered from Deptford and Woolwich in April 1847 as "steam gun schooners", with the intention of ordering four more. They were suspended in August 1847, and the new ships ''Cruizer'' and ''Hornet'' were re-ordered on 1 November 1850. ''Harrier'' was ordered in 1851, ''Fawn'' in 1852, and both ''Falcon'' and ''Alert'' on 2 April 1853. ''Cruizer'' differed from the rest of the class in having a lower-rated geared engine and a displacement of 960 tons, compared to 1,045 tons for the rest of the class.

Propulsion

Their two-cylinder horizontal single-expansion steam engines generated an indicated horsepower of between and ; driving a single screw, this gave a maximum speed of between .

Sail plan

All ships of the class were built with a barque-rig sail plan.

Armament

All the ships of the class were provided with one 32-pounder (56 cwt) long gun on a pivot mount and sixteen 32-pounder (32 cwt) carriage guns in a broadside arrangement. ''Alert'' had her guns reduced to four Armstrong breech-loaders in 1874 as part of her conversion to an Arctic exploration vessel.

Development

The ''Greyhound''-class sloop of 1855 was essentially a ''Cruizer''-class design adapted to carry a more powerful engine developing an indicated horsepower of up to , giving a top speed under steam of . The second and last ship of the ''Greyhound'' class, ''Mutine'', had originally been ordered as the seventh vessel of the ''Cruiser'' class.

Operational histories

''Cruizer''

From 1853 to 1856, ''Cruizer'' took part in the Baltic campaign of the Russian War. Renamed ''Cruiser'' in 1856, she served on the China station during the Second Opium War, including the taking of Canton and the attack on the Taku Forts on the Peiho river in 1859. Laid up in Portsmouth from 1861 to 1866, she recommissioned for the Mediterranean, where she served until 1870. She became part of the Steam Reserve in 1870, but in 1872 she recommissioned in Portsmouth for service as a sail training ship in the Mediterranean, for which role her engines were removed. In May 1893 she was renamed ''Lark'' and in 1912 she was sold at Malta.

''Hornet''

''Hornet'' served in the Baltic in 1854 during the Russian War, and from 1854 until 1859 she served in the East Indies and in China, taking part in the Second Opium War. After a refit in 1859-1860 she recommissioned for the Cape of Good Hope Station and served both there and on the East Indies Station. She paid off at Portsmouth on 22 September 1864 and was broken up by White of Cowes in 1868.

''Harrier''

From 1854 to 1856 ''Harrier'' took part in the Russian War as part of the naval force in the Baltic. She served on the South Atlantic Station before refitting in Portsmouth in 1860. She recommissioned on 29 October 1860 for the Australia Station, where she took part in the New Zealand Wars. Her captain, Commander Edward Hay, was killed on 30 April 1864 during the storming of Gate Pā, and his Coxswain, Samuel Mitchell, was awarded the Victoria Cross for his bravery. ''Harrier'' paid off at Portsmouth on 31 March 1865 and was broken up the next year.

''Fawn''

''Fawn'' commissioned at Sheerness on 30 October 1859 and until 1863 served on the Australia Station. She refitted at Sheerness in 1863, and from 1864 to 1868 served on the North America and West Indies Station. After a second refit at Sheerness in 1869 she went to the Pacific Station, where she remained until 1875. In 1876 she was converted to a survey ship, and in this role she surveyed areas of the east coast of Africa, the Sea of Marmara and the Mediterranean. On 6 April 1883 she paid off, and she was broken up the next year.

''Falcon''

''Falcon'' served in the Baltic during the Russian War before transferring to the North America and West Indies station, where she served until 1857. She refitted in Portsmouth in 1858, then served on the West Coast of Africa from 1859 to 1862. She refitted again in Portsmouth during 1863 before spending the rest of her active life on the Australia Station. During this period she took part in the New Zealand Wars. She paid off at Woolwich on 3 October 1868 and was sold on 27 September 1869 to C Marshall for breaking at Plymouth.

''Alert''

From 1857 to 1868 ''Alert'' served on the Pacific Station, with a refit in Plymouth in 1862. In 1874 she was converted for Arctic exploration; her engines were replaced with R & W Hawthorn compound-expansion engines, she was reboilered to , she was reduced to four guns and her hull was strengthened with felt-covered iron and teak sheathing. The modifications caused her displacement to increase to 1,240 tons. During the British Arctic Expedition of 1875-76 ''Alert'' reached a latitude of 82°N, and her second-in-command, Commander Albert Hastings Markham, took a sledge party as far as 83° 20' 26"N, a record at the time. She was used to survey the Strait of Magellan, as well as Canadian and Australian waters, and on 20 February 1884 was loaned to the US Navy to assist in the rescue of the expedition under Adolphus Greely. In 1885 she was transferred again to the Canadian Government for survey in the Hudson Bay area, on completion of which she was employed as a lighthouse supply vessel and buoy tender. She was laid up in November 1894 and sold, the bill of exchange being forwarded to the Admiralty, since she was still officially on loan. Alert, Nunavut, the northernmost permanently inhabited place on earth, is named after her.
