28 cm Haubitze L/12

The 28 cm Haubitze L/12 was a German siege howitzer. It was developed by Krupp before World War I and saw service in both World War I and World War II. It may have participated in the siege of Sevastopol.

Design and description
The 28 cm Haubitze L/12 was a design of the First World War. Recoil forces were absorbed by a combination of the gun cradle moving up an inclined plane and two hydro-pneumatic or hydro-spring recuperator cylinders, one on each side of the carriage. It was mounted on a turntable which was fixed to a wooden firing platform. For transport it broke down into four loads, the barrel, cradle, turntable and firing platform, each carried by a three-axle trailer. It required three to four days to emplace for firing. An ammunition crane was fixed to the carriage for ease of loading.

It fired a 350 kg high-explosive shell to a range of 10400 m.

Combat history
Supposedly it participated in the assault on Sevastopol in 1942 under the command of 11th Army of Army Group South, but this has not been confirmed.
