21cm Mörser m10-16
The German 21cm Howitzer m/10 (in the German Army named simpley Der Mörser) was the result of ten years development by the firms of Krupp and Rheinmetall. (Its origin was in a Bronze tube Mortar designed in the 1860-ies, and used with full effect first in the Franco-Prussian War of 1870-71.) It was a heavy gun, weighing some 15 tons+, and moved only with the Gun tube transported on a separate Wagon.
The video below, courtesy of Philtydirtyanimal, shows the Mörser in action: <EMBED src=http://www.youtube.com/v/s3uZB1CL4Mw&hl=sv&fs=1 width=425 height=344 type=application/x-shockwave-flash allowscriptaccess="always" allowfullscreen="true"></EMBED> When the War started in 1914, the German Army could field 216 of these big guns, and they were used from the very first days of combat. When the Germans came upon the strong Belgian fortress of Liege, it was these guns that started the attack on August 5th, by sucessfully shelling the forts in the Eastern perimeter, and eventually paving the way for the REALLY big guns, the 42cm Dicke Berthas. It was then used with effect on all fronts, primarily in the Regiments of the Fuss-Artillerie, as one of the standard weapons of indirect fire and support. (The Foot Artillery Regiments - a Corps asset - were the primary units of the heavy German Artillery, each containing two batallions of four batteries each, were the main equipment was 15cm guns. Howitzer Battallions however, had only two batteries per batallion. The number of guns per battery varied between 3 and 4. In a quiet sector, a Division had some 8-9 batteries of 15cm and 21 cm guns in support, but normally some 16 batteries were employed per division.) http://www.patriotfiles.com/forum/imgcacheA/22117.png Experience from the fighting soon made the Artillery men realize that an increase in range would be most helpful, as the comparatively short range of the Howitzer often forced the units to site their guns well within range of most enemy artillery. A small redesign followed: the gun barrel was lengthened somewhat, from L/12 to L/14.5. This new variant was called m/16 or Langer Mörser. However, as the gun already was pretty heavy and cumbersome, the redesign had been done from the premiss that the weight should not be increased. That was pretty much adhered to, but with the effect that the increase in range was even less than one kilometer. Another small redesign, following combat experiences, was the fitting of a Shield. (Some m/10 were retrofitted with this, but not all.) When the war came to an end in 1918, the 21 cm Howitzers of the German Army had fired some 7 million shells. <TABLE borderColor=#996600 cellSpacing=2 cellPadding=4 width=553 border=1><TBODY><TR><TD vAlign=top width="56%">Calibre </TD><TD vAlign=top width="44%"> 211mm </TD></TR><TR><TD vAlign=top width="56%">Weight of Gun (m/10-m/16)</TD><TD vAlign=top width="44%"> 15.49-7.53 tons </TD></TR><TR><TD vAlign=top width="56%">Maximum Range (m/10-m/16)</TD><TD vAlign=top width="44%"> 9.4-10.2 kilometers </TD></TR><TR><TD vAlign=top width="56%">Muzzle Velocity</TD><TD vAlign=top width="44%"> 225-394 metres per second </TD></TR><TR><TD vAlign=top width="56%">Min/Max Elevation</TD><TD vAlign=top width="44%"> +6/+70 </TD></TR><TR><TD vAlign=top width="56%">Weight of Shell</TD><TD vAlign=top width="44%"> 121 kilos </TD></TR></TBODY></TABLE>PLAN OF THE 21 cm MÖRSER The plans below have been made by Ken Musgrave and are his copyright.

Obviously a hurried grouping of the gun: no concealment or earth works to be seen. Point of interest: the gunner pulling the lanyard.</TD><TD align=middle width="33%">A rather blurry photo, I'm afraid, but interesting as it shows a mixture of guns both with and without shield.

A caption connected to the picture states that the guns were performing covering fire during a Retreat Operation. </TD><TD align=middle width="33%">A gun being loaded: four men working the Loading Cradle, one man pushing the projectile into the breech. Note the camouflage netting above the Gun Pit.</TD><TD align=middle width="33%">A Howitzer Model 16 "Langer" - notice the Extra Length of the Barrel. Taken in Flanders (or Artois), and obviously in rather close proximity to the Fighting: notice the devastation and the maximum elevation of the Gun Barrel. Note also the camouflage of the Gun: nice example of a Buntfarben-scheme. If I would hazard I guess, I would say that the base colour is Dark Green-ish, with spots of Lighter Brown and Sand.</TD></TR><TR><TD width="33%"></TD><TD width="33%"></TD><TD align=middle width="33%" height=15></TD><TR><TD width="34%"> Dug in Howitzer firing, probably the same as seen above. The rear, fixed Earth Spade is not used, in fact the whole trail is up in the air: they are obviously relaying on the foldable Earth. (It could also be a so called Siting Shot, where the Spade is forced into the ground by the Recoil.) </TD><TD align=middle width="33%">Here the Gun is broken down, in anticipation of Re-grouping. The Barrel is separated from the rest of the Gun, and dragged away on it's own Wagon. The photo was taken at Estaires, during the Battle of Armantieres.</TD><TD align=middle width="33%">Another Gun, being either dismantled or put together - judging from the lack of hurry, and the Shelter being built on the left, I would put my guess on the later.

Notice the stocky Shell waiting on the ground, and it's transport casing made by wicker. This photo was taken during 1916, during the Battle of Verdun, in what the Germans kalled the Küchenschlucht. The Howitzer belonged to the 1st Bayerische Fussartillerie-Regiment.

All work has been done by the book: the tools and equipment belonging to the gun to the left, shells and gunners waiting a bit off to the right, the wheels of the gun resting on some sort of mat. This photo was taken on the Sereth-front in Romania during the Summer of 1917.</TD><TD align=middle width="33%">A gun well positioned, with dug-in for the crew on the right. A shell is resting on the Loading Cradle, but as the gun is steadily pointing towards the sky, and as there is neither any Gun Layer nor any one ready to push the shell into the breech, this is obviously a staged photo.</TD></TR><TR><TD width="33%"></TD><TD width="33%"></TD><TD align=middle width="33%" height=15></TD></TR></B></B><TR><TD width="34%">A 21 cm mörser being adjusted by the aimer.
