HMS M.33 is one of the few surviving Royal Navy warships from World War I, originally built as an M29-class monitor and launched in 1915. She is best known for her active role in the Gallipoli Campaign, providing naval gunfire support to Allied forces. After the war, M.33 served in various roles, including as a mine-laying training ship, and is now preserved as a museum ship at Portsmouth Historic Dockyard, where she offers visitors a unique glimpse into naval history and the First World War experienc
A Monitor Born of Desperation
HMS M.33 is a survivor—a relic of a class of ships built in haste and designed to die young. Launched in 1915 as part of the Royal Navy’s M29-class monitors, she was one of five vessels ordered by Winston Churchill, then First Lord of the Admiralty, to provide firepower in shallow waters where larger warships dared not venture. Monitors like M.33 were crude but effective: flat-bottomed, lightly armored, and armed with a single 6-inch gun fore and aft, they were built to bombard coastal targets, not to win beauty contests. Their mission was simple—get close to shore, pound the enemy, and retreat before counterfire could respond. M.33 was rushed into service just in time for the Gallipoli Campaign, where she supported the ill-fated landings at Suvla Bay and Anzac Cove, her guns roaring in support of the ANZAC troops ashore
From Gallipoli to the White Sea: A Ship’s Many Lives
After Gallipoli, M.33’s career took her to the frozen waters of Northern Russia in 1919, where she joined a small Allied flotilla supporting White Russian forces against the Bolsheviks during the Russian Civil War. But her story didn’t end there. Unlike most of her sister ships, scrapped after the war, M.33 was repurposed again and again: as a minelayer (renamed HMS Minerva), a training vessel, a fuelling hulk, and even a boom defence workshop. She was the ultimate naval chameleon, adapting to whatever role the Royal Navy required. By the 1980s, she had been saved from the breaker’s yard, first by a preservation trust in Hartlepool and later by Hampshire County Council, which returned her to Portsmouth. After a meticulous restoration, she opened to the public in 2015, her dazzle camouflage and cramped crew spaces offering a vivid glimpse into the harsh realities of life aboard a First World War monitor
A Class of Ships Built to Be Expendable
The M15-class monitors were never intended to last. Their rushed construction and minimalist design reflected the desperation of wartime, and most were scrapped or repurposed within a decade of their launch. Today, only one of these monitors survives: HMS M.33, preserved in Portsmouth Historic Dockyard as a rare relic of the Gallipoli Campaign and the First World War at sea. M.32, like most of her sisters, faded into obscurity, her brief but intense career a footnote in the story of naval innovation during the Great War
A Time Capsule of Naval History
Today, HMS M.33 is one of only three surviving Royal Navy ships from the First World War (alongside HMS Caroline and HMS President), and the sole survivor of the Gallipoli Campaign. Moored in Portsmouth Historic Dockyard, just a stone’s throw from HMS Victory, she is a stark contrast to the grandeur of Nelson’s flagship—a small, utilitarian vessel that tells a different kind of naval story. Her immersive exhibits, including a digital projection of the Gallipoli landings and restored crew quarters, bring her past to life. Visitors can stand on her deck, peer into her 6-inch gun turrets, and imagine the thunder of her broadsides echoing across the Dardanelles. Despite her modest size, M.33 earned a reputation as the "Lucky Ship"—she escaped the heavy losses of Gallipoli and outlasted nearly all her contemporaries, a testament to her sturdy construction and the resourcefulness of those who served aboard her
A Monument to the Forgotten Fleet
HMS M.33 is more than a museum ship; she is a tangible link to a often-overlooked chapter of naval history. Monitors like her were the unsung workhorses of the Great War—unglamorous, expendable, but vital. Her survival is a stroke of luck, her restoration a labor of love. For those who step aboard, she offers a rare chance to connect with the sailors who endured the cramped conditions, the deafening gunfire, and the constant danger of the Gallipoli Campaign. In a dockyard filled with legendary vessels, M.33 stands as a reminder that sometimes, the most extraordinary stories come from the smallest ships
