The duke, after the victory, rode to congratulate Soissons, whose force had not been engaged.

He found the count dead, having accidentally shot himself while pushing up the visor of his helmet with the muzzle of his pistol.
Bouillon soon learned the hollowness of the promises of his allies.
The Spaniards sent neither money nor men, while the Austrians received orders to march away from Sedan and to join the Spaniards, who were marching to the relief of Arras.
The duke, deserted by his allies, prepared to defend Sedan till the last.

Fortunately for him, however, the position of the French at Arras was critical.

The place was strong, two armies were marching to its relief, and it would therefore have been rash to have attempted at the same time the siege of Sedan.

The king himself had joined the army advancing against Bouillon, while the cardinal remained in Paris.
