General comments on this surviving gun :
At the end of the War France ended up with substantial quantities of war material as reparations from Germany. In recognition of Australia’s contribution to the defence of France the French Government gave pieces of artillery to each State. Tasmania’s allocation was this Der Morser. The tube was made by Krupp at Essen in 1917 and is numbered 1001; the carriage was made in 1916 and is numbered 382.

The Der Morser sat for many years at the Hobart Cenotaph before being relocated to Brighton Camp. From there it moved to the Gun Park at Anglesea Barracks before it was moved to its current location at the front of the Barracks complex, facing Davey Street. The gun was thoroughly restored and is in pristine condition (as of January 2020).

The gun has perspex panels over the wheels to stop children from climbing on it.

Historic and technical information
Denomination :     21cm M 16 Origin :       ( Krupp)          

Historic context :

As soon as August 1914, the 21cm M 191O mortars demonstrated their power and mobility in front of the Belgian and French fortresses, in the fall of which they highly contributed. However the transformation of the movement war into a position war and the apparition of better enemy counter-battery fire at the end of 1914 made the APK ('Artillerie Prüfungs Komission') listen to the armies requests and ask to Krupp to study a range improvement to more than 10.000 m. This modernisation mainly consisted into the extension of the tube length from 12 to 14.5, the addition of a protection shield, and some minor modifications gave birth to the and transformed it into the 'langer 21 cm Morser M16', also named 'langer Mörser', one of the most famous aces of the German heavy artillery.

Delivered to the units from the end of 1916, this remarkable weapon provided on all the fronts its impressive destructive power, propulsing its big 120 kg shells being to a distance more than 10 km...

'lange Mörser' was modified a last time in 1917/1918, re-inforcing its wheels system (now steel discs pierced with holes, instead of rod wheels) and its suspension to allow the mechanical towing in a single load by a tractor. The tube could now be moved backwards to lye directly on the carriage trail for transportation. This last version, 100 kg heavier, was named '21 cm Mrs. M17

The long 21cm mortar was built by Krupp to a number of 736 until november 1918. At the Armistice, the german Army was still having 489 suc weapons. Some of them were called back to service during WW2.
