Active was 270feet long between perpendiculars and had a beam of 42feet. Forward the ship had a draught of 16feet, but aft she drew 21feet. Active displaced 3078LT and had a burthen of 2,322 tons. Her iron hull was covered by a 3inches layer of oak that was sheathed with copper from the waterline down to prevent biofouling. Watertight transverse bulkheads subdivided the hull.[1] Her crew consisted of 340 officers and ratings.
The ship had one 2-cylinder horizontal-return, connecting-rod steam engine made by Humphreys and Tennant driving a single 19feet propeller. Five rectangular boilers provided steam to the engine at a working pressure of 30psi.[2] The engine produced a total of 4130ihp which gave Active a maximum speed of 15kn. The ship carried 410LT of coal, enough to steam 2000nmi at .
Active was ship rigged and had a sail area of 16593square feet. The lower masts were made of iron, but the remainder of the masts were wood. The ship's best speed under sail alone was . Her funnel was semi-retractable to reduce wind resistance[2] and her propeller could be hoisted up into the stern of the ship to reduce drag while under sail.
The ship was initially armed with a mix of 7-inch and 64-pounder 64 cwt[3] rifled muzzle-loading guns. The six 7inches guns and two of the four 64-pounders were mounted on the broadside while the other two were mounted on the forecastle and poop deck as chase guns.[4] In 1879, ten BL 6-inch 80-pounder breech-loading guns replaced all the broadside weapons. Two carriages for 14inches torpedoes were added as well.
HMS Active was laid down in 1867 and launched on 13 March 1869. The ship was completed in March 1871 at a total cost of £126,156. Of this, £85,795 was spent on her hull and £40,361 on her machinery. Unlike her sister ship, Active was placed in reserve after completion until 1873 when she was commissioned to serve as the flagship of the Commander-in-Chief, Cape of Good Hope and West Coast of Africa Station, Commodore William Hewett. The ship participated in naval operations during the Third Anglo-Ashanti War of 1874 and some of her crew were landed to reinforce the forces ashore. Commodore Francis Sullivan replaced Hewett in 1876 and he retained command until 1879 when the ship returned home to refit.[5]
Between 19 November 1878 and 21 July 1879, during the Anglo-Zulu War, 173 men of Active (along with men from, and) served ashore as part of an 858-man naval brigade. The group from Active comprised 10 officers, 100 seamen, 5 idlers, 42 Marines, 14 Kroomen, and 2 medical attendants. In addition to small arms, they were equipped with two 12-pounder breech-loading guns, 24-pounder rockets, and a Gatling gun. The 12-pounders were exchanged for two of the Army's 7-pounder mountain guns before entering Zululand.[6]
Attached to the No.1 column commanded by Colonel Charles Pearson, they crossed the Tugela River from Natal into Zululand on 12 January 1879. On 22 January they saw action in the Battle of Inyezane, driving off an attacking force of Zulus with rockets, Martini-Henry rifles and the Gatling gun. The same day the British main force was defeated at the Battle of Isandlwana, and so Pearson's column advanced to Eshowe, where it was besieged for two months, until relieved on 3 April. In February, Active ran aground in Tugela Bay whilst assisting, which had also ran aground. They were refloated 36 hours later.[7] During the campaign, Actives crew suffered only one man killed, and nine wounded in action against the enemy, while nine died of disease during the siege, and one man drowned while crossing the Tugela. In 1881 the South Africa Medal was awarded to those members of Actives crew that had served there.
Active was rearmed and refitted in 1879 and placed in reserve until she was selected in 1885 to be the commodore's flagship in the newly formed Training Squadron. Active was the last square-rigged naval ship to leave Portsmouth Harbour under sail. She was paid off in 1898[5] and was sold for scrap on 10 July 1906.A memorial to the men of Active who lost their lives during the African campaigns can be found in Victoria Park, Portsmouth.[8]
