ORP General Haller

ORP General Haller was a Filin-class guard ship originally built for the Imperial Russian Navy. She was later acquired by the Polish Navy and served until sunk in the Polish Defensive War on 6 September 1939.

History
General Haller was built at Ab Crichton naval yard in Turku, Finland, for the Imperial Russian Navy. She was bought by the Polish Navy in 1921 and she served as a school ship and minelayer.

On 1 September 1939, under the command of Stanisław Mieszkowski, General Haller was patrolling the port of Gdynia, where she was damaged in air attacks. On 2 September, the gunboat was sent to the naval port at Hel. 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. She was left floating until she was sunk on 6 September.
