Battle
Cross the Meuse before the defence can reconstitute itself
Military history
At Sedan, the result does not come from a continuous armoured line. German forces reach the Meuse faster than expected, concentrate infantry, artillery, and the Luftwaffe on several crossing points, then exploit above all the breach opened by the 1st Panzer Division. The French defence has reserves and tanks, but its communications, artillery, and local counterattacks do not create a common barrier in time. The map follows this transformation through the turn westward, without confusing the battle on the Meuse with the whole campaign in France.
The Sichelschnitt plan concentrates Army Group A's Schwerpunkt in the Ardennes, considered difficult for large formations. The documented aim is to surprise the Allied deployment, cross the Meuse, then turn west; it would be excessive to attribute to Falkenhayn or any single decision-maker an unproven psychological formula for Sedan.
French X Corps holds an extended sector around Sedan. The Category B 55th Division is not an empty shell: the AUSA study places it at about 80–85 per cent of establishment, with roughly 13,000 men and 174 guns, while the 71st Division is only partly in position when the blow falls. Depth, armoured reserves, and artillery exist, but linking them is slow.
On 13 May, German action combines bombardment, infantry assault at several sites, and engineer crossings. The 2nd Panzer's assaults at Donchery and the 10th's at Wadelincourt are initially contained; the 1st Panzer's two crossings west of Sedan open the decisive breach. Air effects on communications, artillery, and morale matter, but the sources do not support reducing the breakthrough to the physical destruction of bunkers by Stukas.
On 14 May, the 7th BCC and 213th RI counterattack towards Bulson, while the commitment of the 3rd DCr, although ordered into the sector, is delayed and then fragmented. Fuel, orders, communications, and support do not combine into a single blow capable of throwing the Germans back across the Meuse. The map shows the local action actually undertaken, not a fictitious offensive by the entire 3rd DCr.
