After a very good start Archduke Charles ends the campaign with his army widely dispersed and must withdraw to Linz to allow his army time to regroup if he is to hold the road to Vienna.
This has not been a great campaign for Marshal Oudinot. The Austrian invasion came as a complete surprise, and he was slow to react to it. He then committed his corps piecemeal, resulting in early defeats.
Holding Salzburg was the turning point. Although he did not have a convincing victory at Reishach, his ability to move the Salzburg garrison north meant that the Austrians must retreat beyond the river Salach to avoid disaster.
