The Guns of the SMS Königsberg in German East Africa 1915-17
The Pretoria Gun

This is one of the ten 10.5cm guns salvaged from the wreck of the SMS Königsberg and used in the land campaign in German East Africa during the First World War (see Königsberg Guns Page). Its wartime history is uncertain. All that is known for sure is that the main barrel was once in a turreted position on the SMS Königsberg, that to some extent the displayed gun in Pretoria is a hybrid of at several different original guns and that the plaque describing the history of the gun is almost certainly inaccurate. It is currently on display outside the Union Buildings in Pretoria, South Africa.

The Unions Buildings in Pretoria are the Presidency and official seat of the Government of South Africa. On display outside the buildings is an old gun from the SMS Königsberg.

The barrel of the gun has a flange to hold a barrel shield which would fit inside the turret of the gun when it was originally mounted on the SMS Königsberg. Six of the the ten guns were mounted in turrets and had these flanges, four were mounted in unarmoured cupolas and did not have barrel flanges. This is a useful clue in attempting to identify the guns.

The exact history of this Königsberg gun is uncertain. What is for sure is that it is made up of parts of several different guns as at least four serial numbers (361, 366, 367 and 369) are seen on parts of the gun.

The barrel and left recoil cylinder have the serial number 369, whereas the right recoil cylinder has the serial number 367. The elevation wheel is numbered 361. Many of the bolts on the gun are also numbered (some as 361, 366 and 369).

There is a plate fixed onto the gun identifying it as a "German Naval Gun, Calibre 10.5cm=4.1inches, captured by the SA Mounted Brigade and SA Infantry Brigade Rifles at Kahe, East Africa 21st March 1916".

This is very unlikely to be accurate as the gun captured at Kahe has been seen in period photographs with extensive damage to its breech and a gaping split up the barrel. The Pretoria gun looks relatively intact aside from a missing breech block.

It has Krupp strutted wheels widened with steel bands for use in East Africa.

The carriage itself not a Krupp carriage nor does it look like the carriages made in Dar Es Salaam for other guns (such as those captured at Korogwe, Kibata and Mkuyuni). The main body appears similar to British designs of the period but parts of it are roughly made and welded.

It may be either that this carriage was made with salvaged Krupp wheels separately from the other Dar Es Salaam carriages by the Germans in wartime. Or it may be that it was made by the British or South Africans after the war while reassembling parts of different guns purely for display purposes.

During a 2006 restoration of the gun paint samples were taken and it was found that this reddish brown was the colour as seen during the First World War. It is not known from which part of this hybrid gun that the sample was taken.

Where was gun 369 captured if it was not at Kahe?
There were ten 10.5cm guns on the SMS Königsberg and they all served on land. The ten were put out of action in the following order and places: 1 Kahe, 2 Kondoa-Irangi, 3 Mwanza, 4 Bagamoyo, 5 Mkuyuni, 6 Korogwe, 7 Tabora, 8 Kibata, 9 Mahiwa and 10 Masassi.

Gun 369 cannot be the Kahe gun as we have discussed, the Kahe gun had a large split in the barrel.

It cannot be the gun captured at Mwanza because that is now in Jinja, Uganda.

It cannot be the gun captured at Bagamoyo because that was later seen in London, England and was believed to have been scrapped in Hove during the Second World War.

It cannot be either of the guns captured at Mkuyuni and Kibata because they did not have barrel flanges like the Pretoria gun has.

It cannot be the gun captured at Korogwe because that was later seen on display in the Belgian Congo.

It cannot be the gun captured at Masassi because that also had a very visible split in the muzzle of the barrel caused by the Germans before it was abandoned.

The only remaining options are the guns captured at Mahiwa and Tabora and the gun that was accidentally destroyed at Kondoa Irangi.

It is believed that the Mahiwa gun had no flange but we have not found proof. The Tabora gun was captured by Belgian not British or South African forces. The gun destroyed at Kondoa Irangi was reportedly buried in Dar Es Salaam when it could not be repaired. Thus they are all unlikely options but one of them has to be this barrel.

My own hunch is that this is the gun that was destroyed by an accidental mis-firing in action at Kondoa-Irangi on 18th May 1916. It was taken to Dar Es Salaam to fix it but was deemed to be beyond repair and was buried somewhere near the railways works. Perhaps the locals showed the British where the gun had been buried after the British took Dar Es Salaam in September 1916.

If it was missing a few parts such as a recoil cylinder, carriage and wheels, these could be sourced from other partially destroyed Königsberg guns in British hands (probably the guns captured at Mahiwa, Masassi, Kibata or Mkuyuni).

The Krupp wheels could be from the Kondoa-Irangi gun or salvaged from the remains at Mahiwa or Masassi.

The carriage as we surmised above could have been made by the Germans in wartime or by the British and South Africans after the war to go with the existing barrel and wheels. This is all possible but not yet proven.

The Pretoria Gun, c2005
This photograph shows the Pretoria gun on display at the Union Buildings painted green prior to its restoration in 2006.
Note the shape of the carriage sloping upwards where it meets the barrel. This is unlike any other of the Konigsberg gun carriages and resembles the shape of British gun carriages of the era. Note also recoil cylinders under the breech and the eight strutted Krupp wheels.

The Pretoria Gun, 2006
This photograph shows the Pretoria gun on display shortly after its restoration in reddish brown paint in 2006. Note again the shape of the gun carriage, the eight strutted Krupp wheels and the recoil cylinders now restored to their original brass finish.

The Pretoria Gun, 2012
This photograph shows a frontal view of the gun. Note that the axle runs through the carriage rather than below the carriage as on the Krupp gun carriages. This photo again gives a good view of the steel bands added to the Krupp wheels. The small elevation wheel can just be seen to the right of the carriage. A bar has been added to the display below the carriage to help support the weight of the carraige and barrel.

The Pretoria Gun, 2006
This photograph shows a view of the gun and its carriage from the firer's point of view. Note the breech, recoil pistons and elevation control wheel to the left of the carriage. The widened 25cm steel bands riveted onto the original Krupp wheels can clearly be seen. Note also the brass plaque added to the gun and again the rough construction of the carriage, for example the not-quite-circular shape of the hole in the tail plate.

Breech of the Pretoria Gun
The gun's relatively intact breech. Note horizontally sliding firing block has been removed. This was done by the Germans when they abandoned it so that it did not fall into allied hands while in working order. Note also the recoil cylinder at the bottom of the photo.

Serial Number on the Breech of the Pretoria Gun
The original maker's markings on the breech of the gun: "Nr 369L"- the weapon number, "Fried. Krupp"- Friedrich Krupp AG of Essen- the maker's mark, and "1905"- the date of manufacture.

Note the serial number 361 in the top right corner.

More Serial Numbers on the Pretoria Gun
These photographs show close ups of two bolts on the Pretoria gun with different serial numbers showing them to be from different guns. On the left 366 and on the right 361.

Plaque on the Pretoria Gun
A plate now fixed onto the gun identifying it in English and Afrikaans as a "German Naval Gun, Calibre 10.5cm=4.1inches.Captured by the SA Mounted Brigade and SA Infantry Brigade Rifles at Kahe, East Africa 21st March 1916". As described above this is almost certainly inaccurate.
