The Legacy of HMS Dorsetshire

Today we will be spotlighting HMS Dorsetshire, a heavy cruiser of the British Royal Navy, which has played a significant role in naval operations during the early years of World War II. Commissioned in September 1930, she was the second (and final ship) of the Norfolk subclass within the County-class cruisers. Named after the English county of Dorset, Dorsetshire’s service history was marked by her involvement in the Atlantic and Indian Oceans, overall culminating in her participation in the sinking of the German battleship Bismarck and her own demise in 1942.

Design and Specifications

Constructed at Portsmouth Dockyard, HMS Dorsetshire was launched in January, 1929. As a Norfolk-subclass cruiser within the larger County-class, she was designed for speed and firepower, making her well-suited for both independent operations and fleet support. Some of her unique and salient features include:

  • A main armament of eight 8-inch (203 mm) Mk VIII guns, arranged in four twin turrets.
  • A secondary battery of four 4-inch (102 mm) dual-purpose guns and multiple anti-aircraft weapons to defend against enemy aircraft.
  • A top speed of 31.5 knots (58.3 km/h; 36.2 mph), allowing her to keep pace with the fast-moving naval engagements of the time.
  • A range of 12,000 nautical miles at a cruising speed of 12 knots, making her ideal for long-distance patrols across the British Empire’s vast maritime holdings.
  • Carried two Supermarine Walrus seaplanes, which were launched via catapult for reconnaissance and spotting duties, giving her an edge in locating enemy ships.

Early Service

Upon commissioning, HMS Dorsetshire joined the Atlantic Fleet and later became the flagship of the Commander-in-Chief, Africa, in 1933. In late 1935, she was assigned to the China Station, where she remained until the outbreak of World War II in September 1939. With the onset of hostilities, HMS Dorsetshire was transferred to the South Atlantic to bolster British naval presence in the region.

The Hunt for the Bismarck

Does that name sound familiar to you? If you have been keeping up with our blogs, you’d realise that it is because HMS Birmingham participated in it too! (You may check out our recent blog on it HERE) Circling back on HMS Dorsetshire, one of her most notable engagements occurred in May 1941, during the pursuit of the German battleship Bismarck. With Bismarck sinking HMS Hood in the Battle of the Denmark Strait, the Royal Navy launched an extensive operation to neutralise the threat. Finally, on May 27, 1941, after sustained attacks by British forces had left Bismarck crippled, HMS Dorsetshire was ordered to close in and deliver the final blows! She fired rounds of torpedoes at the incapacitated battleship, contributing to its sinking. Following the engagement, HMS Dorsetshire also rescued 86 German survivors before a U-boat threat forced her to withdraw. 

The Beginning of the End

In March 1942, HMS Dorsetshire was reassigned to the Eastern Fleet to support British operations in the Pacific Theatre. During the Japanese Indian Ocean raid, on April 5, 1942, HMS Dorsetshire and her sister ship, HMS Cornwall, were en route to Colombo when they were spotted by Japanese reconnaissance aircraft. Not long after, more than 50 Japanese Aichi D3A “Val” dive bombers from the carrier Akagi descended upon them. The ships attempted evasive manoeuvre, but the sheer number of attackers overwhelmed their defences. Within just eight minutes, both Dorsetshire and Cornwall were struck multiple times, caught fire, and sank rapidly. Luckily, out of a combined crew of over 1,500, more than 1,100 men were rescued the following day. 

Quick Fun Fact: The Japanese Aichi D3A dive bombers sank more Allied warships than any other Axis aircraft, and was even involved in the attack of Pearl Habour (1941).

Legacy

Retelling HMS Dorsetshire’s service serves as an act of remembrance of the challenges and sacrifices faced by naval forces during World War II. Her participation in the sinking of the Bismarck and her own loss in the Indian Ocean highlight the perils of naval warfare and the strategic importance of cruisers in maintaining maritime dominance. Today, HMS Dorsetshire will forever be remembered for her contributions to the Royal Navy’s efforts during a critical period in history.
