HMS B8 was one of 11

Dardanelles Campaign. The boat was transferred to the Adriatic Sea in 1916 to support Italian forces against the Austro-Hungarian Navy. She was converted into a patrol boat in 1917 and was sold for scrap
in 1919.

Design and description

The B class was an enlarged and improved version of the preceding

draft of 11 feet 2 inches (3.4 m). They displaced 287 long tons (292 t) on the surface and 316 long tons (321 t) submerged. The boats could dive to a depth of 100 feet (30.5 m). The B-class submarines had a crew of two officers and thirteen ratings.[1]

For surface running, the boats were powered by a single 16-cylinder 600-

propeller shaft. When submerged the propeller was driven by a 180-horsepower (134 kW) electric motor. They could reach 12 knots (22 km/h; 14 mph) on the surface and 6.5 knots (12.0 km/h; 7.5 mph) underwater.[1] On the surface, the B class had a range of 1,000 nautical miles (1,900 km; 1,200 mi) at 8.7 knots (16.1 km/h; 10.0 mph).[2]

The boats were armed with two

18-inch (450 mm) torpedo tubes in the bow. They could carry a pair of reload torpedoes, but generally did not as they would have to remove an equal weight of fuel in compensation.[3]

Construction and career

Ordered as part of the 1904–1905 Naval Programme, B8 was built by

Straits of Dover in wartime.[4] On 26 April 1906, B8 ran aground on a mud bank off the entrance to Haslar creek, near Portsmouth. She was floated off at high tide early the next day without sustaining any damage.[5] In 1912, HMS B8, HMS B6 and HMS B7 were transferred to Malta.[4]

After the start of the First World War and the unsuccessful pursuit of the German ships Goeben and Breslau in August 1914, the B-class submarines were transferred to the Dardanelles area in mid-September to prevent any breakout attempt by the German ships. After the arrival of the larger and more modern E-class submarines in early 1915, the B-class boats began to return to Malta. After the Kingdom of Italy joined the Allies in May 1915, the B-class submarines in the Mediterranean were transferred to Venice to reinforce Italian forces in the northern Adriatic.[6] B8, B7 and B9 were the first to arrive in Venice on 11 October, although B8 was immediately sent to the dockyard to repair damage suffered when she collided with the Italian tugboat Luni. B8 was the first British submarine in the Adriatic to sight an enemy warship when she spotted an Austro-Hungarian destroyer off the Istrian coast on 8 November, although she was unable to attack it. The five British submarines made a total of 13 patrols off the Austro-Hungarian coast before the end of 1915, hampered by bad weather and drifting mines, followed by 13 more in the first two months of 1916.[7]

B8 reported spotting a periscope and being missed by a torpedo while beginning a patrol on 28 February; postwar research has revealed that no enemy submarines were in the area where in the incident occurred. By 27 April the boat was being refitted at Venice. After its completion in early May, the boat began her first patrol of the month on the 23rd. She was attacked by the Austro-Hungarian submarine

Paid off at Malta, she was sold for scrap in 1919.[8]
