With a heavy heart, Krabbe was forced to turn over his fortress to the enemy in September, after having written in vain to Corfitz Ulfeldt to be spared from doing so.

In November, he gathered his forces at Uddevalla against a Swedish attack from Vänersborg, but was unable to obtain support from Niels Trolle, the Governor-General of Norway at Akershus Fortress.

Instead, Krabbe received the honor of carrying the blood banner (Danish: blodfanen) at the oath of fealty to Frederick III as hereditary king of Denmark on 18 October.
