After the submarine had been allowed to carry out rudimentary emergency repairs, Trygg escorted her out of Norwegian waters the next day.

After surviving numerous air attacks the ship was finally sunk at Åndalsnes 25 April 1940.

[5] As the torpedo boat was anchored up in the harbour the Luftwaffe bombers first attacked and knocked out British AA positions ashore before turning their attention towards the small Norwegian warship.

A total of sixteen bombs were dropped against Trygg, one hitting the stern of the ship and passing through without exploding.

Before she was sunk Zick managed to slightly damage two of the attacking aircraft with her anti-aircraft armament.
