used, against a railway tunnel near Saumur. The hastily organized night raid was to stop a planned German Panzer Division, travelling to engage the newly landed allied forces in Normandy. The panzers were expected to use the railway to cross the Loire. No. 83 Squadron RAF illuminated the area with flares from four Avro Lancasters and marked the target at low level by three de Havilland Mosquitos. 25 Lancasters of No. 617 Squadron RAF, the "Dambusters" then dropped their Tallboys from with great accuracy. They hit the approaches to the bridge, blocked the railway cutting and one pierced the roof of the tunnel, bringing down a huge quantity of rock and soil which blocked the tunnel, badly delaying the German reinforcements moving towards Normandy, especially 2nd SS Panzer Division Das Reich. The damaged tunnel was quickly dug out to make a deeper cutting, resulting in the need for a second attack. On 22 June, nine Consolidated B-24 Liberators of the United States Army Air Forces used the new Azon glide bombs against the Saumur rail bridge; escorted by 43 North American P-51 Mustangs. They failed to destroy the bridge. During the morning of 24 June, 38 American Boeing B-17 Flying Fortresses with conventional bombs attacked the bridge; escort was provided by 121 of 135 P-51s. The bridge was damaged. The town of Saumur was awarded the Croix de Guerre with palm for its resistance and display of French patriotism during the war. Main attractions Saumur is home to the Cadre Noir, the École Nationale d'Équitation (National School of Horsemanship), known for its annual horse shows, as well as the Armoured Branch and Cavalry Training School, the officer school for armored forces (tanks). There is the national tank museum, the Musée des Blindés, with more than 850 armored vehicles, wheeled or tracked. Most of them are from France, though some come from other countries such as Brazil, Germany, and the Soviet Union, as well as axis and allied vehicles of World War Two. The annual military Carrousel takes place in July each year, as it has done for over 160 years, with displays of horse cavalry skills, historic and modern military vehicles. Amongst the most important monuments of Saumur are the great Château de Saumur itself which stands high above the town, and the nearby Château de Beaulieu which stands just 200 metres from the south bank of the Loire River
