In 1938 Ambrose was renamed HMS Cochrane and converted into a destroyer depot ship. Cochrane survived the Second World War and was scrapped in 1946.
Building
Sir Raylton Dixon and Company of Middlesbrough built Ambrose for £89,000.[1] She was launched on 31 March 1903 and completed that September.[2] Her registered length was 375.2 ft (114.4 m)[3] and she was 387 ft 5 in (118.1 m) long overall.[4] Her beam was 47.8 ft (14.6 m), her holds were 26.4 ft (8.0 m) deep[3] and her draught was 20 ft 9 in (6.3 m).[4] As built, her tonnages were 4,187 GRT and 2,128 NRT.[3]
Ambrose had one screw. The North Eastern Marine Engineering Company built her three-cylinder triple-expansion steam engine.[2] The engine was variously rated as 775 nhp,[5] 800 nhp[3] or 6,350 ihp (4,740 kW). It gave her a speed of 14.5 knots (27 km/h).[4]
Booth's operated scheduled cargo liner and passenger services between Europe and Brazil. In the first decade of the 20th century these services included regular sailings between Liverpool and Manaus, 1,000 miles (1,600 km) up the Amazon River. A Booth passenger ship would leave Liverpool for Manaus on or about the 10th, 20th and 30th day of each month.[6]Ambrose's maiden voyage from Liverpool to Manaus began on either 20 September[7] or 7 October 1903.[1]
In 1906 Ambrose ran aground in Brazil. She had sailed from Liverpool on 30 August, called at Leixões in Portugal, and on 26 September reached Manaus. At 1000 hrs on 3 October she left Manaus on her return journey. At 1515 hrs she reached Para na' Trinidade, some miles downriver on the Amazon, where she ran aground and suffered damage. Ambrose remained at Para na' Trinidade for a week, and reached Liverpool on 27 October.[7]
Booth Line took Ambrose's need for repair as an opportunity to increase her passenger capacity. On 28 October she left Liverpool for Hebburn on the River Tyne, where R&W Hawthorn, Leslie and Company repaired her hull, lengthened her poop deck and added berths for another 150 passengers.[7] The alterations increased Ambrose's tonnages to 4,588 GRT and 2,490 NRT.[8] Work was completed on 30 March 1907 and cost £17,000.[7]
On 11 March off the west coast of Scotland a submarine attacked Ambrose three times. The first attack was at 1320 hrs, when a torpedo missed her bow by 20 yards (18 m). The second attack was at 1405 hrs, when a torpedo passed astern of her. The third attack was at 1422 hrs. On each occasion Ambrose opened fire on the periscope. After the third encounter the attacks ceased, and Ambrose's officers suspected that she had sunk the submarine.[10]
On 6 May submarines attacked Ambrose off Skerryvore.[10]
Ambrose's patrols with the 10th Cruiser Squadron ended in September 1915, when she reached port in Glasgow. On 13 October she transferred to Greenock and on 20 October her crew was paid off.[10] Also on 20 October, the Admiralty bought Ambrose from Booth Line.[12]
Submarine depot ship
In 1917 Ambrose was converted into a submarine depot ship.[14] In this rôle her complement was 238 officers and enlisted men.[4] She was stationed at Berehaven, Ireland in January 1918 and transferred to Falmouth, Cornwall in November. In 1919 she was stationed at Devonport. From 19 September 1918 until 30 October 1920 her commander was CommanderCecil Talbot.
Ambrose spent long periods at the Royal Navy bases in Hong Kong and Weihaiwei. She also visited Kobe and Shanghai in 1920, Nagasaki and Kobe in 1921 and Singapore in 1923.[10]
In 1928 Ambrose and six L-class submarines were recalled to Britain. On this trip the six submarines were HMS L1, L2, L4, L5, L7 and L8. They left Hong Kong on 28 March, reached Singapore on 3 April[21] and left Singapore on 8 April.[22] On 4 December Ambrose was paid off into the Maintenance Reserve at Rosyth.[14]
Final years
On 1 June 1938 Ambrose was renamed HMS Cochrane.[12] Some sources say that she was converted into a destroyer depot ship.[1][2] Another source describes her Second World War rôle as a "base ship".[2] In 1940, her Bomb Disposal Officer was responsible for the defusing and removal of a German shell that hit HMS Prince of Wales but did not explode during her fight with the battleship Bismarck in 1940.
