Description

The Maginot-era improvements to Sarts comprise two combat blocks. The ouvrage was built within the walls of the old Fort des Sarts. An underground gallery connects the two blocks. A second phase was planned to provide two artillery blocks armed with one 75mm twin gun turret each, as well as an entry block outside the walls of the old fort.

In the Second World War, the Battle of France was the German invasion of France and the Low Countries, beginning on 10 May 1940, which ended the Phoney War. The battle consisted of two main operations. In the first, Fall Gelb , German armoured units pushed through the Ardennes, to cut off and...

 in 1940, the invading German forces approached Maubeuge from the south and east, to the rear of the defensive line. The German 28th Infantry Division moved along the line of fortifications 19-22 May, rolling up blockhouses and larger fortifications. Les Sarts first took fire on 21 May, with a Stuka raid on 22 May. Heavy fire from the rear continued on 23 May, gradually reducing the fort's defenses. At 1100 hours, with all means of resistance gone, les Sarts surrendered, the last ouvrage of the defenses of Maubeuge to do so.

Current

Les Sarts is not accessible to the public. It is reported to be in poor condition, with all metal salvaged.
