During sea trials, "Nestor" was called on to make several deployments north of the British Isles, in poor conditions. On 14 May, the sailors aboard mutinied in response to the heavy drinking sessions of the ship's captain and two other senior officers: they locked themselves in their accommodations and refused to man the ship until the officers were removed. The ship's doctor visited the admiral at Scapa Flow (where the ship was based); the admiral sent marines to arrest the three officers, and appointed a new commander to "Nestor".
