kildaremark Posted 6 October , 2014 Share Posted 6 October , 2014 Information on trench mortar batteries seems very scarce. I have gone through the various war diaries of 35 Division and got a good general feel for their development from 1916 onwards, their usage in wire cutting, trench raids, collaboration with brigade and divisional artillery as the medium batteries moved from control under Infantry brigades to the ammunition column to the divisional artillery. A number of publications with the customary page or two on trench mortars are slightly at odds with what happens on the ground in terms of the development of trench mortar batteries. Has anyone a copy of GHQ O.B/166 9 March 1916 "Medium & Light Trench Mortar Batteries - Policy and Organization" ? Can anyone refer me to any document that gives the names of gunners in any medium battery i.e. RFA and RGA to see an example of the split between the services? Is there any record of the renaming of the batteries from March 1916, for example No. 68 and No. 71 TM batteries became X/35 and Y/35 TM batteries with Z/35 newly formed while V/35 was not formed until September 1916. Has anyone carried out any decent research on TMBs and willing to share! Thanks Mark Link to comment Share on other sites More sharing options...
kevinrowlinson Posted 6 October , 2014 Share Posted 6 October , 2014 Hi Mark, Here are a few I have made a note of. Not sure whether they will be of help. 22 TMB formed 303-1915, later renumbered 91 TMB 5 TMB became 1 Y TMB 2 TMB became 1 X TMB 64 TMB became 1 Z TMB 20-3-1916 308 TMB becomes 3 Z TMB 40 TMB became 3 Y TMB Possible 43 TMB became 3*, mentioned in 50 Div diary March 1916 87 TMB? formed 11-8-1916 in diary became 5 X TMB 5 Division 90 TMB became 5 Z TMB from Aug 1916 5 Y TMB 52 TMB, became 300 TMB became 6 Z TMB 300 TMB became 6 Z TMB 410 TMB became 7 X TMB 113 TMB became 7 Y TMB 22 TMB became 91 TMB Aug 1915 became 7? 36 TMB becomes 8 X TMB 65 TMB became 8 Y TMB 6 TMB became 12 Y TMB 10 TMB becomes 12 Z TMB 39 TMB, 14 Z TMB?? 3 TMB became 15 X TMB 20-3-1916 63 TMB became 15 Z TMB 20-3-1916 27 TMB became Y 17 TMB 50 TMB becomes 17 Z TMB 97 TMB became 18 Z TMB 99 TMB became 18 Y TMB 11 TMB became 19 Y TMB 4 TMB became 19 X TMB 14 TMB formed 7-7-1915 20 TMB became 24 X TMB 98 TMB became 32 X 88 TMB becomes 32 Y TMB 2-9-1915 9 TMB became 33 X TMB 20-3-1916 61 TMB becomes 34Y TMB 68 TMB becomes 35 X TMB 71 TMB becomes 35 Y TMB 67 TMB becomes 38 Y TMB 20-3-1916 8 TMB became 47 Y TMB 29 TMB became 50 Y TMB 31 TMB became 50 X TMB 50 Z formed 2-4-1916? 32 TMB 5 Division I think the early batteries were predominately made up by volunteer gunners, with a few infantry as well, so I would imagine no two batteries had the same number of gunners from one corps. Of the two or three diaries I have seen only one gave a gunners number and corps when being transferred or was injured, but as it obviously did not have a nominal roll it would be impossible to say what percentage were RGA and RFA in the whole battery.

Don Posted 6 October , 2014 Share Posted 6 October , 2014 Kevin,thats great research,fantastic.Mark,as Kevin says,it was a mixed bag of RGA and infantryMy grandfather Tom Walsh RGA 30315 was in several batteries in 1915,he was in TMB,22,32,42,and a nominal batt.He was a regular before the Great War. I have his service record.He was back and forward to the TM school.I got the impression from his record and the TMB diary,22,32,that they were very much at a experimently stage until the Stokes mortar took the lead.I can send you his record if you like so you can see his movements between TMBs.RegardsGerry Link to comment Share on other sites More sharing options...
kildaremark Posted 6 October , 2014 Author Share Posted 6 October , 2014 Thanks Kevin and Gerry, That's a hell of a lot of TMBs! I had assumed that there were circa 50-60 mediums before they were renumbered in March 1916 but clearly with triple digits there was something else going on. I've also noticed that casualties seem surprisingly low for front line troops who were prime targets for counter battery work. The emplacements must have been well built.

researchingreg Posted 6 October , 2014 Share Posted 6 October , 2014 During a visit to the IWM i saw this quote by the Stokes mortar display naming an officer (if this helps) ' .....Mortar Fire usually drew swift retaliation from the enemy. British Officer Edward Beddington Behrens described mortar crews as "the suicide club....desperate men, brave as anything, rather nervy though"' Also during the same visit I noted that a Lt Col James Jack, had commented on the devastating effect of the Minenwerfers on British Trenches. It might be worth looking up these two men! Link to comment Share on other sites More sharing options...
kevinrowlinson Posted 7 October , 2014 Share Posted 7 October , 2014 Thanks Kevin and Gerry, ......but clearly with triple digits there was something else going on. Mark Mark, I suspect, but have no evidence to prove whether it is true, but would suggest that the triple digit numbers were the type of mortars they were using. Obviously this may have only lasted for a short time until they changed to divisional identification. The AA batteries did similar with numbered batteries starting at 200 using different guns. Viz. 308 TMB was number 8 TMB of a particular model of mortar. I may be completely wrong though. Needs further research. Kevin Link to comment Share on other sites More sharing options...
battiscombe Posted 7 October , 2014 Share Posted 7 October , 2014 I have 2 TMB formed mainly of RFA early 1915, but replacements coming in soon from RGA , from Base 22nd TMB - a Trench Howitzer Bty.. formed from RGA [this usually seems to be the case in the early units identified as 'Trench Howitzer Bty' ].. lots of RGA in Btys in the 20s.., also 32nd Tr How Bty 35th Tr How Bty not untypical ... 8/7/1915: formed at Berthen : Lt T G Du Boisson RHA, 1 Sgt, 4 Cpls, 17 gunners RGA from some records I have of later units most of 34th Div TMBs and 39th Div TMBs for example look to be mainly RFA rather than RGA.. many later [1916+] units were formed by men drawn from the DACs, who were ready sources of manpower .. so RFA some Divisional records [CRA] also record when TMBs are being formed and where men are found to serve in them .. i think most of the later Corps Heavy TMBs were RGA manned Link to comment Share on other sites More sharing options...

But it is a great first hand account of life in WW1. Richard Link to comment Share on other sites More sharing options...
Chasemuseum Posted 29 October , 2014 Share Posted 29 October , 2014 Within the Australian context, trench mortar crews had two polite nicknames which have been recorded "The shoot and scoot mob" and "the duckboard harriers", due to the tendency to draw retaliatory fire. By all accounts they were very unpopular with the infantry who had to stay and wear ”the hate“. I suspect that there were a number of less polite names which have not been recorded.

roytoner Posted 13 March , 2015 Share Posted 13 March , 2015 anyone know how many men a Light Trench Mortar Battery would have at full complement? I've read of 69 men in a Canadian unit - is that near the mark? Interested in the 34th LTMB at Thiepval Ridge in late September 1916. They got off lightly compared to the 34th's infantry battalions in terms of those killed but would like to work out what % were wounded. 34th Brigade's diary lists 1 killed, 19 wounded and 2 missing Link to comment Share on other sites More sharing options...
Ron Clifton Posted 13 March , 2015 Share Posted 13 March , 2015 Hello kildaremark From research I did some years ago at Kew, the numbering of TMBs went up to 114, although there were some gaps, notably in the 50s and 70s. I'm inclined to agree with Kevin that numbers in the 300s and 400s were not sequential. When the allocation of TMBs was formalised in mid-1916, brigade TMBs were ligt, equipped with the Stokes, and were manned predominantly by infantrymen. Medium and heavy TMBs, at divisional level, were regarded as units of the RFA and RGA respectively, though this did not mean that there was no mixture of RFA and RGA men among them - in fact, that seems to have been quite common. The heavy TMBs were generally cosolidated as Corps-level units in 1918. Roytoner Here are the original War Establishments for various types of TMB. There were only minor changes thereafter: September 1915 Trench Mortar Battery (4 mortars of the same type)2 Officers, 1 Serjeant, 4 Corporals or Lance-Corporals, 16 Privates, 2 Batmen.August 1916 Light Trench Mortar Battery (2 sections, each 4 x 3" Stokes mortars)Captain, 3 Subalterns, 2 Serjeants, 8 Corporals or Lance-Corporals, 32 Privates, 4 Batmen.August 1916 Medium Trench Mortar Battery (4 x 2" mortars)2 Officers, 1 Serjeant, 4 Corporals or Bombardiers, 16 Privates, 2 Batmen.August 1916 Heavy Trench Mortar Battery (4 x 9.45" mortars)Captain, 2 Subalterns, 3 Serjeants, 1 Fitter, 4 Corporals, 4 Bombardiers, 47 Gunners (incl 3 telephonists), 2 Orderlies, 1 Clerk, 1 Cook, 3 Batmen.

battiscombe Posted 14 March , 2015 Share Posted 14 March , 2015 Further to this previous post, and useful list, I find in 25th Division CRA files some records that suggest that 28th Trench Mortar Bty (1 1/2 "), 30th Trench Howitzer Bty (2") and 49th Trench Mortar Battery ('4 pdr') all landed up with 25th Division by November 1915 and latterly became X/25, Y/25 and Z/25 in spring 1916 - when in that division each Bty was attached to a RFA Brigade with a regular system of rotation of officers and men between Bdes and TMBs with 1 month tours.. all RFA subalterns were expected to be sent to TM School for a TM course.. and an explicit note that "Officers commanding RFA Brigades should make certain that only good men are selected for duty with Trench Mortar Batteries" Hi Mark, Here are a few I have made a note of.

Y2 TMB Posted 17 April , 2015 Share Posted 17 April , 2015 Y2 TMB, picture taken in 1916 post Delville Wood, my grandfather served in both X and Y 2nd Div TMB's he volunteered previously being a Driver in the Divisional Ammunition Column. When first established they used a variety of different weapons including "French Aerial Torpedoes" his words I don't have a clue what they were. In the early days they did have the worst of it, the German Mine Thrower being a much better weapon than anything the Allies had. Link to comment Share on other sites More sharing options...
Martin Feledziak Posted 17 April , 2015 Share Posted 17 April , 2015 That is a great photograph. are the torpedoes weapons that were sent out and head height with the intention of taking out wire defences ? - It is a great image Thanks for sharing.

Ron Clifton Posted 18 April , 2015 Share Posted 18 April , 2015 Hello Martin The British did use "Bangalore torpedoes" but these were not an aerial weapon. They basically consisted of a length of drainpipe packed with explosive, which could be slid under a barbed wire entanglement and detonated, thereby - in theory at least - cutting the wire.

Colin W Taylor Posted 18 April , 2015 Share Posted 18 April , 2015 The Germans used trench mortar s which fired bombs which were described by the British as aerial torpedoes but I couldn't match this to a certain German TM weapon though. The French presumably used a similar type of TM in this case. This is completely different to a Bangalore Torpedo, which is as Ron describes.

Y2 TMB Posted 19 April , 2015 Share Posted 19 April , 2015 My research so far into 2nd Div TMB batteries during the Somme period seems to indicate an even spread of Gunners and Drivers all RFA men. Casualties reflect this 5 Drivers, 4 Gunners, 1 Bombadier and 1 Corporal all RFA men. My research is confined to 2nd Division Batteries during the Somme 1916 and may well not reflect what was going on elsewhere. Link to comment Share on other sites More sharing options...
