The Siege of Maubeuge: When Belgium's Forgotten Fortress Bought Time for the Marne

A garrison of 45,000 held out for thirteen days against Germany's unstoppable juggernaut — and changed the course of World War I

A forgotten French fortress held out for 13 days against German siege guns — buying crucial time for the Miracle of the Marne.

The German shells began falling on Maubeuge at dawn on August 25, 1914. Inside the ring of outdated forts surrounding this French border town, Governor General Fournier peered through field glasses at the gray columns snaking toward his position. He commanded 45,000 men — mostly French reservists and Belgian refugees who had fled Liège — and a chain of Victorian-era fortifications that military planners had already written off as obsolete.

What followed would become one of the war's most consequential forgotten stands.

The Germans had expected Maubeuge to fall in two days, just as Liège had crumbled before their massive 420mm siege howitzers — the dreaded 'Big Berthas.' They brought seven of these monsters to Maubeuge, each capable of hurling shells weighing nearly a ton. The fortress's concrete cupolas, designed to withstand the artillery of 1880, should have shattered like eggshells.

But Fournier's men refused to cooperate with German timetables.

💡 The Germans fired over 7,000 heavy artillery shells at Maubeuge — yet one fort, Fort de Leveau, was so thoroughly buried in rubble that its garrison of 200 men remained trapped alive underground for three days after the surrender, unaware the siege had ended.
