• Armour is weak against battleship-calibre guns
• Outgunned by battleships, battlecruisers, and some American heavy cruisers

History

The Treaty Cruiser

The 1921 Washington Treaty conference aimed to prevent war between the major naval powers by restricting warship construction. It decided that cruiser displacement should be limited to a maximum of 10,000 tons per ship. Britain had set the pace by constructing the Hawkins class – the most modern and capable cruisers of their time – which displaced close to 10,000 tons. It was known that the USA and Japan would soon match, and probably exceed, them, building 10,000-ton cruisers with 8-inch guns (the Hawkins-class ships carried 7.5-inch main guns). The British answer was heavy cruisers of the County class, constructed in three batches that were to be armed with 8-inch guns and would be fast with long range. At the end of 1923, the British administration gave the building of eight County-class cruisers known as Kent class (Kent, Suffolk, Cumberland, Berwick, and Cornwall), with two extras (Australia and Canberra) for the Royal Australian Navy. They were laid down between July 1924 and September 1925 and completed between July 1927 and July 1928. Next came the London class (London, Devonshire, Shropshire, and Sussex), laid down between March 1926 and February 1927 and completed between January and September 1929.

The most obvious difference between the London and Kent classes was the removal of a protective bulge on the waterline, which forced a modified hull design that increased length by 2 feet 8 inches and incorporated internal bulges. Their high freeboard meant they were, in most weather, dry ships and could keep up a good rate of knots even in heavy seas. The beam of the Kent was 2 feet 5 inches wider than the London. HMS London's displacement was 9,850 tons (standard) and 13,315 tons (full load). She was 632 feet 8 inches in length, with a 66-foot beam and a draught of 20 feet 9 inches. Propulsion was provided by Parsons geared turbines and eight Admiralty three-drum boilers. HMS London could carry 3,190 tons of oil and achieve more than thirty-two knots. In addition to eight 8-inch main guns and four 4-inch high-angles, London also had four 2-pounder guns and eight 21-inch torpedo tubes. The bridge and the foremast of the London-class cruisers were set further aft to allow B turret to fire abaft the beam without blasting the bridge.

HMS London in the 1930s

For her first overseas deployment, HMS London was sent to the Mediterranean, where she became the flagship of the First Cruiser Squadron and activated in the following years. Trouble was brewing on the island of Cyprus in the early 1930s and soon boiled over into insurrection. It had been granted Crown Colony status in 1925, after being taken from the Turks and occupied by British forces in the First World War. Its position in the eastern Mediterranean made it an ideal base from which to provide additional security for British interests in the Middle East, such as the Suez Canal and Palestine. A strategically vital oil pipeline terminated at Haifa, and the island was also an important staging post for travelers heading to Britain's empire in Asia. Having cast off the hated Turks, Greek Cypriots were angry and frustrated at being prevented by British rule from uniting with their ethnic homeland of Greece. A decision by the Crown Colony administrators to raise taxes stoked the fires of resentment. On 21 October 1931, a mob gathered and marched on the Governor's residence. They burned it to the ground and then went on the rampage when the police belatedly intervened.

The Royal Navy was asked to aid the civil powers, with HMS London and her sister ship HMS Shropshire sent to suppress the uprising in company with the destroyers HMS Acasta and Achates. At Larnaca, HMS London landed armed shore parties of Royal Marines and sailors to protect government offices. They found the local population still defiant and capable of violence. The protestors hurled verbal abuse at London's marines and sailors, waving the Greek flag in their faces. Stones rained down on the helmets of the British, but they held firm. The rioters were trying to make the marines and sailors lose their cool and open fire in the hope that Greece might protest and even intervene militarily. In the early hours of 25 October, the revolt leaders were arrested by troops and police. They were taken by boat to London and Shropshire, where they were held in the cruisers' wardrooms' convivial surroundings. The detainees were given every hospitality, including good food and drink. A few stiff whiskies helped steady the nerves of those still a little shocked at being hauled from their beds in the wee small hours. The seizing of the leaders took the steam out of the revolt, and the British warships were soon able to depart the island's harbours, leaving a job well done behind them.

On 18 July 1936, the Fascist General Franco led an uprising by twelve military garrisons on mainland Spain and five in Spanish Morocco. Most of southern Spain fell to the Fascists, and outside forces intervened to stoke the fires of conflict – the Germans and Italians on the Fascist side and Russia on the Republican government side. Thousands of British passport holders were at the mercy of various warring factions, and the UK government responded by sending warships, including HMS London, to evacuate them from danger, using Barcelona and Valencia as points of embarkation. The ship stopped at Malta for supplies and then went on to Barcelona in company with the Devonshire. On 22 July, the cruiser was secured by her stern to the Mole in Barcelona harbor and the ship received reports from ashore saying the city was now quiet after savage fighting.

…one regiment of Fascists was annihilated in a square, being mown down by concealed rifle fire.

As London waited for the evacuees to start arriving, the situation grew more volatile. On 23 July, a bomb from an aircraft landed near a British warship patrolling the Straits of Gibraltar. HMS London was informed that Barcelona's British Colony of 1,000 people, including many nuns, was to be evacuated. By midnight on 23 July, only 200 people had turned up, with forty of them being immediately sent to Marseilles aboard the destroyer HMS Douglas, which had come alongside London to take them off.

At the beginning of August, the Italian and Swiss governments ordered all their nationals out of Spain. London was flooded with desperate people, and Commander Wright gave up his cabin to a refugee family, ending up sleeping on the upper deck by X-turret. London was told on 7 August that she would stay another fifteen days in Barcelona. After returning to Gibraltar, she was to head back to Portsmouth for a refit that was due to commence in November, during which she was to receive four more high-angle 4-inch guns. By mid-August, it was apparent to Captain Wright that an increasing number of the 'British' refugees were bogus:

13 August…. The 'British' folk leaving Spain nowadays are not good speakers of English!

On 22 August, HMS London was pleased to note that HMS Shropshire had arrived in Barcelona to relieve herself. Between 23 July and 29 July, 839 refugees were evacuated via HMS London, and a further 1,000 were sent to safety between 30 July and 21 August.

At the end of 1936, HMS London was tasked with hunting down gunrunners in Western Mediterranean. Her aircrafts located a suspicious-looking vessel that could well have been a gunrunner, but the cruiser caught up after five hours of hard steaming, only to discover that it was not the suitable quarry at all. In 1937 HMS London was called back to Britain for celebrating the coronation of King George VI and another major refit.

The Reconstruction

With war clouds gathering fast in the late 1930s and naval construction restrictions being discarded equally rapidly, the decision was taken to reconstruct the County-class cruisers to make them more capable ships. HMS London was the first, paying off into refit at Chatham in March 1939. Her ambitious rebuild proved complex and lasted until February 1941. Among the significant modifications were a new waterline armour belt and bridge superstructure, additional 4-inch guns, new hangars and aircraft catapult (the original had been fitted in 1932), and new engines. Her top speed was to remain more than thirty-two knots, and she would be able to do twenty-four knots using just half her boilers. Having started her life with a displacement of 9,850 tons (standard) and 13,315 tons (deep load), by the end of the refit, HMS London's tonnage was 11,015 tons (standard) and 14,578 tons (deep load). The severe changes in London's silhouette included removing one of her funnels, with the new catapult occupying space between the remaining two. Grouped around the aft funnel were the new 4-inch guns, in twin mountings, with pom-pom anti-aircraft weapons (sixteen 2-pounders) on the hangar roofs and machine guns fitted on top of X and B turrets. Post refit, HMS London carried eight 21-inch torpedoes in quadruple mountings on the upper deck and had depth charges. The onset of hostilities between Britain and Germany in September 1939 meant the remaining County-class cruisers were too busy to be rebuilt along the same lines as London. And, as we will see later, it was just as well, for London's rebuild would not stand up to the strain of war service.

The London's lines were altered dramatically by her major rebuild.

During the reconstruction, German bombers targeted Chatham frequently and air raids often interrupted the work, delaying London's progress. The cruiser was finally commissioned for service with the Home Fleet on 7 February 1941.

On 5 March HMS London left Chatham. Waiting for her in the familiar waters of the Channel were magnetic mines sown by the Germans and E-boats keen to pounce on her. The cruiser indulged in some simple deception to ensure she got away from Chatham safely, heading for Tilbury instead of going straight out to sea to avoid German spies and scout planes. Leaving the Thames on 6 March, on her way north, HMS London passed a couple of sinking ships which had been unlucky, falling victim to mines or E-boats.

After arriving at Scapa Flow, London embarked on an energetic program of work up exercises. These included sub-calibre and full calibre shoots with her main guns at targets and also throw off shoots. The latter entailed her guns having their controls set to throw off shells by a cable's length (200 yards) astern, even though the weapons were aimed right at the target ship. London was soon on the receiving end of this all too realistic gunnery exercise technique, when she acted as a target for the battleship Rodney's 16-inch guns. Among other battlewagons the London provided a target for, were King George V, Hood and Prince of Wales.

On 2 April, the London left Scapa to rendezvous with the carrier HMS Argus, which was being used to ferry fighter planes to the Mediterranean. The cruiser escorted Argus to a point 300 miles west of Lisbon where she was turned over to the care of HMS Sheffield.

HMS London spent some time with the battleship King George V keeping watch on Brest to ensure the German battlecruisers Scharnhorst and Gneisenau remained bottled up. The two German heavy ships had taken refuge at the French naval port in February 1941 and would be there for another year. Relieved of this duty, London's next mission was escorting slow convoys out of Sierra Leone. This was difficult for the ship to deal with, as the merchant vessels could do little more than six knots and she tended to wallow at such a slow speed. To relieve the tedium, and provide a means of boosting the confidence of the merchant ships, HMS London ran up and down the convoy lines at twenty-two knots, then took a circuitous route, before going back to the center.

On 12 May, at a UK port, London embarked soldiers who were being taken south to Gibraltar. The generous internal proportions of the County-class cruisers made them ideal troop carriers. After offloading her 600 Army passengers at Gibraltar, London stayed in port for a few days, as she was due to return to Britain carrying soldiers going home on leave. Together with the cruiser HMS Edinburgh, she was also to provide escort for a UK-bound convoy that included the liner SS Arundel Castle, carrying evacuees from Gibraltar. Shortly before the cruiser left, Italian aircraft tried to bomb the Rock, but hit a nearby Spanish town by mistake, killing a number of people. London's AA guns went to action stations but the planes were too far away to shoot down. Sailing north from Gibraltar, on 23 May, London encountered a Vichy French ship that she stopped and searched.

Hunt for Bismarck, and all the troubles

Shortly before 5 P.M., on 24 May, London received a order to take over shadowing duties, searching for the German battleship Bismarck, which was cornered and destroyed on 27 May, leaving HMS London re-ordered to search for German supply ships in the central and southern Atlantic.

On 31 May, HMS London called in at Bathurst, Gambia, to land some of the troops embarked at Gibraltar. They were grateful to escape the confines of the cruiser, but not exactly pleased at being further away from Britain than when they had started. Their chances of spending their leave with their families looked rather slim. HMS London sailed again that afternoon, heading for a rendezvous on 3 June with the destroyer HMS Brilliant, which would be her hunting partner. The following day at 07° 35' N – 31° 29' W, the two British warships found their first German supply ship, the 17,000 tons Esso Hamburg, which had, in fact, refueled the Prinz Eugen on the morning of 28 May. The oil transfer had been curtailed when the German cruiser's lookouts spotted smoke on the horizon.

Smoke rose from the sinking German supply vessel Esso Hamburg.

The British ships soon set the German supply ship on fire and picked up surviving German sailors. But the Esso Hamburg was being very stubborn, so HMS Brilliant fired a torpedo into the supply ship, which failed to go off. Next, she poured fire from her 4.7-inch guns into the German vessel, which caught fire and sank. Unfortunately, the huge pillar of smoke from burning oil curling up into the sky was a perfect warning sign for any other German vessels lurking in that stretch of ocean.

On 5 June HMS London found the supply ship, Egerland, which was flying the Panamanian flag. In an effort to prevent her from scuttling herself London opened fire on her at a very long range and the shot went through her bridge and set her on fire. The German vessel's crew set scuttling charges and abandoned ship, with several more boatloads of Germans taken aboard the already crowded London. Many of the new POWs were U-boat crews who had been waiting for submarines to turn up.

Blessed with enough able-bodied sailors to keep her underway, HMS London headed to Freetown in Sierra Leone to offload her passengers and for part of the way she helped escort a convoy heading in the same direction. London left the convoy on 7 June and went ahead.

During a brief stay in port, the London offloaded the remainder of her British troops onto HMS Norfolk, which was heading back to the UK, while the Germans were sent to prison camps. Back at sea, HMS London resumed her search for German supply vessels. On 12 June the Friedrich Breme had been sunk by the cruiser HMS Sheffield while, on 15 June, the Lothringen had been located and destroyed by planes from the carrier Eagle assisted by the cruiser Dunedin. Six days later, close to the equator, HMS London found the Babitonga, another German supply ship. As it appeared the small German merchant ship posed no threat, London's off watch sailors were allowed to come up onto the upper deck to watch her being sunk.

The County-class cruisers, also known as the A-Type cruisers, were the first British cruiser vessels to be developed in the interwar period of the 1920s. Their design being heavily influenced by the restrictions imposed by the Washington Naval Treaty, meant that British shipbuilders had to find compromises during development in order to comply with the treaty as well as to meet the requirements of the Royal Navy for a ship capable of trade route protection.

This resulted in the creation of a ship design with good cruising range and adequate firepower, but very light armour protection in order to stay within treaty restrictions. The orders for the first ships were placed in the mid 1920's and construction began in 1924.

HMS London (C69) was laid down in February 1926 and commissioned into service in January 1929 as the lead ship of the second batch of County-class cruisers to be built, known as the London subclass. During the 1930's, HMS London took part in a goodwill visit to Venice and assisted in the evacuation of civilians from Barcelona during the Spanish Civil War, before being sent to drydock for refit in 1939.

In 1941, HMS London took part in the hunt for the battleship Bismarck, after which the ship was once again dry-docked for repairs. The following year, HMS London assisted in escorting several convoys in the Atlantic, after which she was assigned to South African waters in 1943, before joining the Eastern Fleet. HMS London continued serving in the postwar years, during which the ship got involved in an incident in Chinese waters in 1949 which left it heavily damaged. Being deemed uneconomical for repairs, HMS London was sold for scrap in January 1950.
