Construction of The Mole off the Zeebrugge Coast

The aptly-named Mole is a crescent-shaped concrete breakwater viaduct, jutting in a north-easterly direction towards the North Sea. It was originally built to protect Zeebrugge Harbour from the harsh North Sea storms that swept in from the west.

Concluding with a lighthouse at one end, the Mole is 1.5 miles in length and sturdily built. It was completed in 1903 to great ceremony by King Leopold III of Belgium. But little did anyone realise at the time, that the German forces would utilise it as a fort, heavily guarded by 1000 men and countless battery-guns. The lighthouse formed the ideal watch-post against allied invasions from the sea.
Entrance to the Bruges Canal
The causeway running along the Mole had been laid with a road and a railway within the shadow of a 15 foot concrete wall, 10 feet thick on the seaward side. This provided protection from the inclement weather (and during wartime) allied invasion. Incredibly, the top of the wall provided a secondary roadway and a further wall, 4 feet higher than the wall at its base.
Any raiding vessel stood little chance of overcoming the strong ocean tides, harsh sea gales, countless gun emplacements, cannons, nets and artillery. And this without being spotted first by powerful searchlights or the lighthouse itself.
Captain Roger Keyes, chosen to raid the Zeebrugge Mole on St George’s Day 1918, must have been too aware of the challenges that he faced.

Roger Keyes’ Strategy on the Zeebrugge Raid: Blockships and a Smokescreen

In World War I, Captain Roger Keyes was chosen to storm the Bruges canal in Belgium that provided exits to the open seas via Ostend and Zeebrugge. The German flotilla has used the Zeebrugge Mole as a convenient sanctuary from which to launch Uboats and sink allied ships passing through the English Channel. By 1918, Britain was virtually held under siege by the menace of the German Uboats.

The crews of the flotilla were looked upon with disdain, almost as pirates. Such an action as torpedoing passing vessels from the concealment of the sea was seen as unethical and cowardly. By this time, they had already sunk over 2,500 allied ships.
In order to block the Bruges canal entrance, Keyes perfected a plan to use retired mining vessels: HMS Thetis, Iphignia and Intrepid, which would become ‘blockships’ by scuttling. A storming of the Mole by means of HMS Vindictive with the aid of two Mersey ferries, HMS Iris II and HMS Daffodil would provide the diversion needed.
Scuttling Blockships
In the meantime, two submarines loaded with explosives would breach the Mole wall, providing access to the Bruges canal. Behind the resultant smokescreen, Vindictive would offload 200 royal marines who would disable the gun emplacements lining the Mole. The three blockships would also be scuttled in place, closing off the Bruges canal.
Keyes had already been to the Zeebrugge Mole in 1914 when on board HMS Lurcher during the Battle of Heligoland Bight, so he knew the layout of the area. He also knew the blockships had to have the right girth – just wide enough to enter the canal, but not so narrow that the smaller boats could pass through. Each blockship would be filled with concrete, making them virtually impossible to move once scuttled. Both Ostend and Zeebrugge would be raided simultaneously to give the enemy no chance to clear either end.
Zeebrugge Raid Outcome
Sadly, the outcome of the raid was vastly different to the plan. The wind changed direction during Vindictive’s approach, clearing the smokescreen and providing a clear view of the raiding marines. HMS Thetis was not scuttled in the right place, leaving the canal entrance partially open and allied marines suffered heavy casualties.
Despite the failure of the mission, Captain Keyes and his staff were lauded as heroes and Churchill declared that the Zeebrugge Raid was the ‘finest feat of arms’.

Roger Keyes and the Zeebrugge Raid: Biography in Brief

ROGER JOHN BROWNLOW KEYES was already an experienced admiral prior to the Zeebrugge Raid. Born in the Punjab in 1872, he was only 13 years old when he began his Royal Navy career as a cadet. He steadily worked his way up, becoming lieutenant of HMS Turquoise at the tender age of 21.

(The Seafarers) Arthur Corbett Smith
Fourth born to Sir Charles Patton Keyes, this British-Indian officer’s son declared from an early age he wanted to go the family way and serve the British Empire. And to this end, he became a confident and audacious naval officer who feared no challenge or opposition as he travelled throughout Europe, Africa and Asia. 

Chief missions include the suppression of the Slave Trade from Zanzibar, key involvement in the Dardanelles Campaign, commander of the Dover Patrol on the South coast of England, the Zeebrugge Raid in Belgium and the capture of Chinese destroyers during the Boxer Rebellion in 1900.
Keyes' Naval Career Upturn
Keyes feared mockery least of all, proving wrong his incredulous Russian naval staff when he disabled the Boxer defences who besieged parts of Peking after terrorizing Western nationals.
Keyes’ bold approach against the Boxer uprising formed the turning point in his career and he earned prestigious appointments within the Royal Navy, commanding numerous destroyers and battleships. In 1916, he inevitably earned a Distinguished Service Order for action in armed combat.
And yet, Keyes was already a naval veteran prior to the Zeebrugge Raid in 1918. Keyes loved the sea and he embraced any mission, no matter how formidable. His involvement in the Battle of Heligoland Bight in 1914, for instance, resulted in the sinking of several German vessels with the loss of 1000 German soldiers, but not without significant losses of his own men.
A year later, Keyes was appointed Chief of Staff to the Gallipoli Campaign, although his proposals to attack the Turkish forts from the rear were never carried out. Much of his frustration lay in his inherent need to ‘get things done’ rather than take the so-called unimaginative and stodgy approach of some of his bureaucratic fellow officers.
Sea Mines at the Straits of Dover
Keyes was the natural choice for the storming of Zeebrugge and Ostend, being pragmatic and experienced in raiding stratagems. But first, Keyes closed off the Straits of Dover to the German Uboats sneaking through allied defences at night. Keyes’ intelligent strategy involving the laying of sea mines at various depths sunk several German submarines within a mere month.
However, Keyes was almost drowned soon after when the seaplane he was travelling in had to crash land due to engine failure. But his greatest challenge was yet to come, as his flagship. HMS Warwick provided a conspicuous target for the German naval men stationed on the Mole off the coast of Zeebrugge. Keyes was consistent in his offensive approach and demonstrated to the public his iron will and determination, as well as that of his crew.
Although the outcome of the Zeebrugge Raid saw limited success – the German officers were able to clear the Bruges channel after being scuttled by allied blockships – Keyes was seen as a national hero along with his fleet.
Keyes' Later Life
Keyes continued in his involvement in the training of commandos in the raiding of hostile locations and also commanded various battlecruisers between the wars before becoming Admiral of the Fleet in 1935. But he saw little action at sea from then on, involving himself in politics and becoming MP for Portsmouth North. Active on the debate on the government’s effectiveness in war tactics, he was instrumental in Churchill’s rise.

Keyes proposed plans to raid Nazi occupied ports in Europe during World War II, but the chief of staff saw Keyes as being reckless and his plans were turned down. Replaced by Lord Louis Mountbatton as the director of Combined Operations Headquarters, Keyes felt betrayed by those he had supported.
To appease Keyes’ disillusionment, the title ‘Baron Keyes of Zeebrugge and Dover’ was offered. Keyes closed his career via a farewell tour around Canada, New Zealand and Australia on board HMS Appalachian. Sadly, Keyes suffered lung damage after inhaling aircraft smoke from Japanese aircraft and never fully recovered. He died of a heart attack a year later in 1945.
Through all the action Keyes had seen, he still wished to be buried amongst the men who had given their lives to the Zeebrugge Raid in 1918.

HMS Vindictive British Cruiser Prior to the Zeebrugge Mole Attack

British Naval Ship HMS Vindictive Prior to the Zeebrugge Raid

At the end of her career, HMS Vindictive was reinforced for the attack on the Zeebrugge Mole. In the same year, soon after, she was scuttled as a blockship inside the Ostend submarine harbour. A memorial stone to the vessel is now at Ostend. This picture was taken in December 1897.

Sentinel type class vessel: 5.750 tons in weight; 320 feet in length, the Vindictive was sunk as a blockship at Ostend on May 10 1918.

The other blockships used on the Zeebrugge Raid were HMS Thetis and Iphigenia. Both were Apollo class British light cruisers, sunk as blockships at Zeebrugge in April 1918.

Scuttled Naval Ship HMS Intrepid in the Mole after the Zeebrugge Raid 1918

British Naval Vessel HMS Intrepid Scuttled on the Mole Coast

A dramatic view of the scuttled British naval vessel, HMS Intrepid after the Zeebrugge offensive in 1918. The Ship, having served its purpose, lays derelict without a soul in sight within the Mole entryway.

This photograph gives an extended view of the Zeebrugge Mole in 1918. The three casual men in oil-soiled clothes and caps looking up at the photographer are mostly likely naval mechanics.

Their easy attitude and the empty shell case suggest the Zeebrugge raid of St George’s Day 1918 has already occurred.
