Battle
Cross the Meuse before the defence can reconstitute itself
Military history
At Sedan, German infantry crosses the Meuse before the tanks. On 13 May, bombardment and assault create a bridgehead that engineers connect to the starting bank. Armour crosses before French reserves can intervene together. The local counterattack at Bulson fails; the 1st and 2nd Panzer Divisions can turn west while the 10th protects the southern flank. The outcome rests on this sequence of crossings, support and reactions that turns the breach into an exploitation route.
The German plan concentrates a major effort by Army Group A in the Ardennes. A rapid arrival at the Meuse is intended to surprise the Allied deployment, enable a crossing and then open an advance west. Roads and communications make this concentration possible while leaving long columns vulnerable to delay.
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.
