Reinforcements under Enghien, dispatched by Mazarin in the hopes of saving Freiburg, arrived days too late. The Bavarians were well entrenched in the mountains around Freiburg. Nonetheless, Enghien (who has assumed command) determined to make a frontal assault.
The attacks were made on 3 August and 5 August, 1644. The battle was bloody but equivocal in result: each side lost roughly half its army and each remained on the field.
Freiburg remained in Bavarian hands, blunting by its closeness to Breisach the advantages possessing that place presented.
