Artillery Order of Battle, Tobruk Fortress, 5 November 1941

The OOB below is from the war diary of the Commander Royal Artillery (CRA) of Tobruk Fortress (TobFort) command, which was provided by the divisional command of British 70 Division. 70 Division was reinforced by a number of artillery regiments, and the Polish Carpathian Brigade, which in turn included the Polish Carpathian Artillery Regiment.

The OOB does not include the ‘bush guns’ which were captured Italian equipment used by the frontline infantry battalions. I do believe however that the 100mm guns included in the OOB are captured Italian materiel.

What is noticeable otherwise is the mix of guns. There are eight different types. What is also noticeable is the very low number of heavy calibre guns. Essentially just 4x 149mm, also the 4.5” guns and 60-pdr were also considered ‘medium’ by the Royal Artillery. The besieging Axis forces were far better equipped with heavy artillery, which would have given them a fair advantage in particular in counter battery work.

The gun total was 88 field guns of various calibres and 16 medium guns on 5 November. This compares to 72 25pdr field guns in a typical infantry division at the time. The total was broken down as follows:

64x 25pdr

8x 18pdr (A.Tk. – but were used also for thickening up barrages)

8x 4.5” hows

8x 75mm (not sure if these were captured Italian, or the venerable French mle1907, I presume the latter)

4x 149mm

4x 4.5” guns

4x 60pdr

4x 100mm (I count these as medium, and would presume they are captured Italian equipment. There were six of these guns still in service with TobFort in February 1941 – see here)

On 16 November, 20 new 25pdr guns were received by the fortress, which had to be assembled first. They were landed from what the war diary says was a minelayer, but probably were A-Lighters and a storeship. They were assigned as follows:

12x Polish Carpathian Artillery Regiment, where I presume they replaced the 8x 75mm and 4x 4.5″ howitzers.

8x 144 Field Regiment (where they replaced the 18pdr which went in reserve and pure anti-tank roles, and were immediately committed)

The rapid deployment of these guns shows that there were no reserve field guns in the fortress.

Regarding A.Tk. guns from 149 A.Tk. Rgt, these are not mentioned in the document, but I would presume that this was a 48 gun regiment, with 3 troops of 4 guns to each battery, for a total of 48 guns. The artillery statement for 8 Army of 4 November gives this regiment 40x 2pdr and 9x 18pdr, with another 8 guns being in transit to Tobruk, which would confirm the organisation as a pure 2-pdr regiment with the 18-pdrs attached as supernumeraries to the regiment. When 144 Fd. Rgt. retired 8 18pdr guns, this would have meant there were enough 18pdrs to make up a full battery of 16 guns, similar to the other 64 gun regiments. The war diary of 149 ATk Rgt refers a few times to portees and towers, indicating that it actually operated both the 2pdr (which would have been porteed) and the 18pdr (which would have been towed).

While this indicates that this is all the AT of Tobruk this is not the case. While 149 A.Tk. Rgt. controlled the AT of TobFort, there was a considerable amount of AT guns in the three AT companies under the infantry brigades, and then the ‘bush guns’ within the infantry battalions, although their AT value would have been negligible to non-existant.

The table is reduced from the original table, I have removed the location statements, and merged troops into batteries where they had the same equipment, even if they were at different locations.

  1. Andreas,

    I don’t think the infantry battalions had their own AT guns, they had been centralised into the Brigade Coys.

    Regards,
