ORP General Haller was a Filin-class guard ship[1] originally built for the Imperial Russian Navy.

General Haller was built at Ab Crichton in Turku, Finland, for the Imperial Russian Navy.

On 1 September 1939, under the command of Captain Stanisław Mieszkowski, General Haller was patrolling the port of Gdynia, where she was damaged in air attacks.

There she was turned into a floating battery, until on 3 September, after major bomb damage, all the guns were stripped and added to the defences on land.
