ianjonesncl Posted 17 June , 2010 Share Posted 17 June , 2010 Pals Reading the Official History for the Somme in 1916, chapter XII on the preliminary bombardment details the tasks including; "shelling of communications every night (but lacrymatory shell was not to be used until midnight on Y/Z day)" What type of shell was this ? Is it a from of tear gas ? (Collins dictionary of, Lacrymatory - causing, or producing tears) Which weapon systems fired this type of shell ? Any help much appreciated.

centurion Posted 17 June , 2010 Share Posted 17 June , 2010 Putting tear gas into perspective "The low concentration required (one part in ten million of some lachrymators is sufficient to make vision impossible without a mask) makes this form of gas warfare very economical as well as very effective. Even if a mask does completely protect against such compounds, their use compels an army to wear the mask indefinitely, with an expenditure of shell far short of that required if the much more deadly gases were used. Thus Fries estimates that one good lachrymatory shell will force wearing the mask over an area that would require 500 to 1000 phosgene shell of equal size to produce the same effect. While the number of actual casualties will be very much lower, the total effect considered from the standpoint of the expenditure of ammunition and of the objectives gained, will be just as valuable."

ianjonesncl Posted 17 June , 2010 Author Share Posted 17 June , 2010 Pals Many thanks. Does anyone know which weapon systems were capable of firing those shells ? Link to comment Share on other sites More sharing options...
David B Posted 17 June , 2010 Share Posted 17 June , 2010 The Germans normally used 150 mm (5.9 inch) guns to deliver shells. I presume the llies used much the same size weapon systems. David Link to comment Share on other sites More sharing options...
centurion Posted 17 June , 2010 Share Posted 17 June , 2010 German gas shells were based on the Kopfkammer Schrapnell with the lead or antimony balls being replaced by a glass container, as such they were also available in 7.7 cm Link to comment Share on other sites More sharing options...
centurion Posted 17 June , 2010 Share Posted 17 June , 2010 I believe that there was a British 18pdr gas shell, like the German based on the shrapnel round. I think the 60 pdr also fired a gas shell. By WW2 gas shells came in 25 pdr, 5.5 and 6 inch sizes so I imagine the WW1 equivalents applied. Link to comment Share on other sites More sharing options...
ianjonesncl Posted 18 June , 2010 Author Share Posted 18 June , 2010 Thanks to everyone for the information. A quick check shows the following had Gas Shells; 4.7 inch Gun 60 Pounder 8 inch Howitzer 18 Pounder 4.5 inch Howitzer Link to comment Share on other sites More sharing options...
dman Posted 19 June , 2010 Share Posted 19 June , 2010 The definative reference is "CHEMICALS IN WAR" by Lt Col A.M. Prentiss (later Brig General) PHD, USA publshed in 1937 Can be found in some large university libraries. Goes in detail of all chemical weapons in use during WW I. gas, incendiary, flame warfare. Gives dimensions of all chemical shells, their construction and fillings. Very informative. Link to comment Share on other sites More sharing options...
Hans k. Posted 19 June , 2010 Share Posted 19 June , 2010 Regarding Centurion's mention of gas shells with inserted glass containers, I know that the Germans used this delivery system for diphenylchlorarsine which was a sternutator (irritant) but also described in some sources as a lachrymator. These shells were designated "blue cross" by the Germans and so marked. Below is one of these glass bottles shown next to a GM17 gas mask for scale. German gas shells were based on the Kopfkammer Schrapnell with the lead or antimony balls being replaced by a glass container, as such they were also available in 7.7 cm Link to comment Share on other sites More sharing options...
Cnock Posted 19 June , 2010 Share Posted 19 June , 2010 Hi, by the way, the 'Blauwkreuzkampfstoff' also named Clark 1, was not liquid and needed no bottle. one of its characteristics was to enter the filterbox and cause irritatian of nose, eyes and bronchial tubes, forcing the victim to take his gasmask of. That is why the Germans called it 'Maskenbrecher'. With the mask taken of, other types of lethal gasses could do their deadly work Cnock Link to comment Share on other sites More sharing options...
Hans k. Posted 19 June , 2010 Share Posted 19 June , 2010 (edited) Who said Blaukreuz was a liquid? The fact that it was contained inside a glass bottle is well documented, as are the bottles themselves. As a side note, the clip-on attachment on the filter of the gas mask shown in my previous thread was specifically designed to keep the sternutator dust from entering the mask via the filter. Hans Edit: someone removed this diagram of the Blaukreuz shell I originally posted. Edited 14 May , 2017 by Hans k. Link to comment Share on other sites More sharing options...

Rob Connolly Posted 21 June , 2010 Share Posted 21 June , 2010 Thanks to everyone for the information. A quick check shows the following had Gas Shells; 4.7 inch Gun 60 Pounder 8 inch Howitzer 18 Pounder 4.5 inch Howitzer But not during the battle in question. I'm reading the second OH volume about the Somme, and it specifically states for an engagement before 14/7/1916 that gas shells were fired by attached French batteries, since the British did not have this latest form of disagreeableness.
