The smaller of the two main Verdun forts, Fort de Vaux was the scene of a week-long German siege in June 1916 that became one of the symbols of French resistance. After running out of water, food and ammunition, Major Raynal surrendered with full military honours. Crown Prince Wilhelm reportedly returned Raynal's sword to him in recognition of the defence.
The visit follows the fort's claustrophobic corridors, the gun turrets, the underground galleries, the gas-filled compartments where soldiers died. There is a memorial plaque to Vaillant the pigeon at the entrance. Less crowded than Douaumont and more intimate; allow 90 minutes including the walk around the exterior. Open daily except Mondays in winter.
