The President Masaryk was a river monitor of the First Czechoslovak Republic, serving from 1932 until the dissolution of the republic in 1939. With four 66-millimetre (2.6 in) guns[1] in two twin turrets,[2] it was that nation's most powerful warship of the 1930s and flagship of the Czechoslovakian river flotilla.[1] After the German occupation, the ship was taken into the German army under the name Bechelaren and fought against the Soviets. It was scrapped in 1978.

Service in Czechoslovakia

In the 1920s, the Czechoslovakian naval forces operated river craft inherited from the Austro-Hungarian Empire. These being obsolescent, in the late 1920s plans were made to build two new large river patrol craft. Only one of these, the President Masaryk, was built.[2]

The design of the President Masaryk was based on the Austrian monitor Catfish (German: Wels).[4] It was designed at the Skoda Works and built at the Škoda shipyard in Komárno. The flat-bottomed hull was divided into 15 watertight compartments.[3]

Various Czechoslovakian (and other) companies contributed components to the vessel: Poldi Kladno supplied steel plates, the Škoda works at Plzeň the engines, and the Hamburg company Zeis the marine propellers.[4] Yarrow boilers were installed on the vessel.[1] The ship was laid down (started) in August 1929[3] and launched in 1930[1] or 1931.[2] Trials showed that the ship did not perform to specifications, so it was returned to the shipyard for major modifications. Among other changes, the single stack was replaced with dual stacks, one for each engine.[4] These modifications being completed, and the ship's speed increased from 13.8 knots (25.6 km/h) to 16.7 knots (30.9 km/h),[4] the President Masaryk was commissioned in 1932. After this it patrolled the Danube River from its base in Bratislava[4] for the rest of the First Czechoslovak Republic's existence. The President Masaryk was the only Czechoslovakian ship able to match the best ships the other Danubian powers (Yugoslavia, Romania, and Hungary) in the 1930s.[3]

Career in German service

After the German invasion of 1939, the ship was used by the Germans. Until 1941 it was based in Linz and continued to patrol the Danube. In 1941 it was transferred downriver to the area of Yugoslavia (which had been overrun by the Germans).

In 1943 the vessel was returned to Linz and underwent extensive modernization. The hull was lengthened by 30 centimetres (12 in), the shape of the stern was changed, and new machinery was installed, with the boilers and engines replaced with two MAN submarine diesel engines with an output of 1,800 horsepower each. The stacks were removed and replaced with exhaust pipes on the sides of the vessel. The single rudder was replaced with two.[3] Using space freed up by the changes in propulsion machinery, a quadruple mount with four 20mm flak guns was installed. A separate 20mm cannon on the stern was replaced with a 37 flak gun, and the machine gun turret at the front was removed.

In 1944 the Bechelaren was returned to duty on the lower Danube. On the night of April 5–6, 1944, while escorting a convoy, the vessel was damaged by planes of the Red Air Force. After repairs, it was returned to service at Visegrád in Hungary. Later it returned to Linz, where (since 66mm ammunition was no longer being manufactured) its four 66-millimetre (2.6 in) guns were replaced with two 88-millimetre (3.5 in) naval guns with light shields.

The Bechelaren then participated in combat operations in Yugoslavia and Hungary. In 1944 it supported the German counterattack toward Budapest and at Melk in Austria it fought Soviet gunboats, sinking two. This was the Bechelaren's last combat mission.

Final years

On May 11, 1945, the Bechelaren's crew surrendered the ship to the United States Army in Linz. In 1947 the ship was returned (without weapons) to Czechoslovakia and taken to Bratislava, where in 1951 it was restored to working condition, but was never re-armed.[4] The Czechoslovakian Army having no further use for the vessel, it was sold to the civilian sector in 1955. The hull then served as hulk for storage and workshops at the Komárno Shipyard. In 1978 the President Masaryk was scrapped.
