HMS Iron Duke

HMS Iron Duke






There, she inflicted significant damage on the German battleship SMS König early in the main fleet action. In January 1917, she was relieved as the fleet flagship.


She also assisted in the evacuation of refugees from Smyrna.

In 1926, she was assigned to the Atlantic Fleet, where she served as a training ship. Iron Duke remained on active duty for only a few more years;


Iron Duke was therefore converted into a gunnery training ship; her armour and much of her armament were removed to render her unfit for combat.


She continued to serve as an anti-aircraft platform for the duration of the war and was eventually refloated and broken up for scrap in the late 1940s.

Each turret was also fitted with a 15-foot rangefinder.





The main conning tower was protected by 13 inches of armour.


HMS Dreadnought

HMS Dreadnought



Dreadnought’s primary armament was a suite of ten 45-caliber Mk X 12-inch (300 mm) guns, arranged in such a way that only eight of her main guns could fire a broadside and a secondary armament of ten 50-caliber 12-pounder guns and five 18-inch (460 mm) torpedo tubes.




From 1907 until 1911, Dreadnought served as the flagship of the Home Fleet until being replaced by HMS Neptune (1909) in March 1911.

Dreadnought was then assigned to the 1st Division of the Home Fleet and was present at the Fleet Review for the coronation of King George V.

In December 1912, the ship was transferred from the 1st Battle Squadron and became the flagship of the 4th Squadron until 10 December 1914.

While patrolling the North Sea on 18 March 1915, she rammed and sank U-29, becoming the only battleship to have sunk a submarine.

Dreadnought did not participate in the Battle of Jutland as she was undergoing a refit.

Two years later, she resumed her role as flagship of the 4th Squadron, but was moved into the reserve in February 1920 and sold for scrap on 9 May 1921.

She was broken up on 2nd January 1923

HMS Agincourt

HMS Agincourt


Originally part of Brazil’s role in a South American naval arms race, she holds the distinction of mounting more heavy guns (fourteen) and more turrets (seven) than any other dreadnought battleship, in keeping with the Brazilians’ requirement for an especially impressive design.

Brazil ordered the ship in 1911 as Rio de Janeiro from the British company Armstrong Whitworth.

However, the collapse of Brazil’s rubber boom and warming in relations with Argentina, the country’s chief rival, led to the ship’s sale while under construction to the Ottoman Empire.

The Ottomans renamed her Sultan Osman I, after the empire’s founder, and the ship was nearly complete when the First World War broke out.

The British government seized her for use by the Royal Navy, together with another Ottoman dreadnought being constructed in Britain.

This act caused resentment in the Ottoman Empire, as the payments for both ships were complete, and contributed to the decision of the Ottoman government to join the Central Powers.

Renamed Agincourt by the Royal Navy, she joined the Grand Fleet in the North Sea.

During the war, the ship spent the bulk of her time on patrols and exercises, although she did participate in the Battle of Jutland in 1916.


First Battle of the Atlantic

The Battle of the Atlantic during World War 1

The Atlantic U-boat campaign of World War I (sometimes called the “First Battle of the Atlantic”, in reference to the World War II campaign of that name) was the prolonged naval conflict between German submarines and the Allied navies in Atlantic waters—the seas around the British Isles, the North Sea and the coast of France.

Initially, the U-boat campaign was directed against the British Grand Fleet.

Later U-boat fleet action was extended to include action against the trade routes of the Allied powers. This campaign was highly destructive and resulted in the loss of nearly half of Britain’s merchant marine fleet during the course of the war.

To counter the German submarines, the Allies moved shipping into convoys guarded by destroyers, blockades such as the Dover Barrage and minefields were laid, and aircraft patrols monitored the U-boat bases.

The U-boat campaign was not able to cut off supplies before the US entered the war in 1917 and in later 1918, the U-boat bases were abandoned in the face of the Allied advance.

The tactical successes and failures of the Atlantic U-boat Campaign would later be used as a set of available tactics in World War II in a similar U-boat war against the British Empire.

On 6 August 1914, two days after Britain had declared war on Germany, the German U-boats U-5, U-7, U-8, U-9, U-13, U-14, U-15, U-16, U-17, and U-18 sailed from their base in Heligoland to attack Royal Navy warships in the North Sea in the first submarine war patrols in history.

The U-boats sailed north, hoping to encounter Royal Navy squadrons between Shetland and Bergen.

On 8 August, one of U-9’s engines broke down and she was forced to return to base. On the same day, off Fair Isle, U-15 sighted the British battleships HMS Ajax, HMS Monarch, and HMS Orion on maneuvers and fired a torpedo at Monarch.
This failed to hit and succeeded only in putting the battleships on their guard.

At dawn the next morning, the 1st Light Cruiser Squadron, which was screening the battleships, came into contact with the U-boats, HMS Birmingham sighting U-15, which was lying on the surface.

There was no sign of any lookouts on the U-boat and sounds of hammering could be heard, as though her crew was performing repairs.

Birmingham immediately altered course and rammed U-15 just behind her conning tower. The submarine was cut in two and sank with all hands.

On 12 August, seven U-boats returned to Heligoland; U-13 was also missing, and it was thought she had been mined. While the operation was a failure, it caused the Royal Navy some uneasiness, disproving earlier estimates as to U-boats’ radius of action and leaving the security of the Grand Fleet’s unprotected anchorage at Scapa Flow open to question.

On the other hand, the ease with which U-15 had been destroyed by Birmingham encouraged the false belief that submarines were no great danger to surface warships.

First successes On 5 September 1914, U-21 commanded by Lieutenant Otto Hersing made history when he torpedoed the Royal Navy light cruiser HMS Pathfinder. The cruiser’s magazine exploded, and the ship sank in four minutes, taking 259 of her crew with her.

It was the first combat victory of the modern submarine. The German U-boats were to get even luckier on 22 September. Early in the morning of that day, a lookout on the bridge of U-9, commanded by Lieutenant Otto Weddigen, spotted a vessel on the horizon. Weddigen ordered the U-boat to submerge immediately, and the submarine went forward to investigate.

At closer range, Weddigen discovered three old Royal Navy armoured cruisers, HMS Aboukir, HMS Cressy, and HMS Hogue. These three vessels were not merely antiquated, but were staffed mostly by reservists, and were so clearly vulnerable that a decision to withdraw them was already filtering up through the bureaucracy of the Admiralty.

The order did not come soon enough for the ships.

Weddigen sent one torpedo into Aboukir.

The captains of Hogue and Cressy assumed Aboukir had struck a mine and came up to assist. U-9 put two torpedoes into Hogue and then hit Cressy with two more torpedoes as the cruiser tried to flee.

The three cruisers sank in less than an hour, killing 1,460 British sailors.

Three weeks later, on 15 October, Weddigen also sank the old cruiser HMS Hawke, and the crew of U-9 became national heroes. Each was awarded the Iron Cross Second Class, except for Weddigen, who received the Iron Cross First Class.

The sinkings caused alarm within the British Admiralty,[ which was increasingly nervous about the security of the Scapa Flow anchorage, and the fleet was sent to ports in Ireland and the west coast of Scotland until adequate defenses were installed at Scapa Flow.
This, in a sense, was a more significant victory than sinking a few old cruisers; the world’s most powerful fleet had been forced to abandon its home base. End of the first campaign These concerns were well-founded.

On 23 November U-18 penetrated Scapa Flow via Hoxa Sound, following a steamer through the boom and entering the anchorage with little difficulty. However, the fleet was absent, being dispersed in anchorages on the west coast of Scotland and Ireland.

As U-18 was making her way back out to the open sea, her periscope was spotted by a guard boat. The trawler Dorothy Gray altered course and rammed the periscope, rendering it unserviceable. 

U-18 then suffered a failure of her diving plane motor and the boat became unable to maintain her depth, at one point even impacting the seabed.

Eventually, her captain was forced to surface and scuttle his command, and all but one crew-member were picked up by British boats.

The last success of the year came on 31 December.

U-24 sighted the British battleship HMS Formidable on maneuvers in the English Channel and torpedoed her. Formidable sank with the loss of 547 of her crew.

The C-in-C Channel Fleet, Adm. Sir Lewis Bayly, was criticized for not taking proper precautions during the exercises but was cleared of the charge of negligence.

Bayly later served with distinction as commander of the anti-submarine warfare forces at Queenstown.

The Battle of Jutland

The Battle of Jutland during World War 1

The Battle of Jutland was a naval battle fought between Britain’s Royal Navy Grand Fleet, under Admiral Sir John Jellicoe, and the Imperial German Navy’s High Seas Fleet, under Vice-Admiral Reinhard Scheer, during the First World War.

The battle unfolded in extensive maneuvering and three main engagements (the battlecruiser action, the fleet action, and the night action), from 31 May to 1 June 1916, of the North Sea coast of Denmark’s Jutland Peninsula.

It was the largest naval battle and the only full-scale clash of battleships in that war. Jutland was the third fleet action between steel battleships, following the long-range gunnery duel at the Yellow Sea and the decisive Battle of Tsushima in 1905, during the Russo-Japanese War.





The Germans planned to use Vice-Admiral Franz Hipper’s fast scouting group of five modern battlecruisers to lure Vice-Admiral Sir David Beatty’s battlecruiser squadrons into the path of the main German fleet.




On the afternoon of 31 May, Beatty encountered Hipper’s battlecruiser force long before the Germans had expected. 



Beatty’s withdrawal at the sight of the High Seas Fleet, which the British had not known was in the open sea, would reverse the course of the battle by drawing the German fleet in pursuit towards the British Grand Fleet.

Between 18:30, when the sun was lowering on the western horizon, back-lighting the German forces, and nightfall at about 20:30, the two fleets—totaling 250 ships between them—directly engaged twice.


After sunset, and throughout the night, Jellicoe maneuvered to cut the Germans off from their base, hoping to continue the battle the next morning, but under the cover of darkness, Scheer broke through the British light forces forming the rearguard of the Grand Fleet and returned to port.

Both sides claimed victory.


The British press criticised the Grand Fleet’s failure to force a decisive outcome, while Scheer’s plan of destroying a substantial portion of the British fleet also failed.
