Remembered Today:

What does P M and S mean in an artillery war diary?


MrEd

Recommended Posts

Wondering what these mean, are they types of shells?

the war diary has the following entries in it, repeated on 120 odd pages.

 

8th and 9th/8/17 - 74 SB fired 400 P on Glencourse Wood
                            - 118 SB fired 200 M on Glencourse Wood

                            - 275 SB fired 554 S on Glencourse Wood

 

Now i know SB is siege battery, but what are the P M and S? I presume types of shell and the figure refers to number?

I can post a small example screengrab of the War Diary but wasnt sure on copyright so have just transcribed it

Thanks

Which war diary. I assume 53 HAG?

I would agree number is probably rounds but like you am stumped by the letter! Would like to be educated also.

As you probably know the three batteries were equipped with different Howitzers, I don't know if this helps.

The amount for the 8" Howitzers looks impressive.

Would have been my first guesses.

But I don't think we had Mustard until November.

I'm reasonably certain an 8" Howitzer never fired Shrapnel. As far as I remember Britain was well behind with gas shell development at this point in the war the Livens projector being the main delivery system.

The only thing that springs to mind is M for Mellinite.

Is it 400 F rather than 400 P?

 

The letter codes define specific natures of ammunition: M is 9.2" Howitzer HE; S is 8" Howitzer HE; F is 6" Howitzer, Light, HE. 

The decode for P is actually 2.75" Shrapnel (used in the 2.75" Mountain Gun).

It could possibly be an F - am I allowed to take a screengrab of a representative passage from the war diary and put it up here? It’s a pdf from the NA

There is no problem with putting up one page from a war diary.

Okay here is a screen grab of a representative entry, it’s definitely a ‘P’

6" Howitzers.  Are they firing P as well?

Yes, I'd agree that looks like a P, which is at odds with the list of shell codes. Are there other examples throughout the diary?

 

Yes. It’s repeated numerous times and always next to a number ‘xxx battery fired xxx P on polygon wood’ etc

Thanks peter - in the WD it mentions ‘252 now 6 howitzers’ 

 

i wasnt sure if that was 6 in number or 6 in size of calibre - am I right in saying that they would have 6, 6 inch howitzers in the battery?

 

252 was firing ‘P’ whatever that was

In 1917 all the batteries except 275 had 4 howitzers.  275 SB was made up to 6 on 6th June 1917. The other batteries went from 4 to 6 during the first few months of 1918.

In concert with the other howitzers, the 6" would have been firing either light or heavy HE. If the intention was cratering, rather than penetrating to destroy deep bunkers, then light shell would have been the choice. It would be interesting to find a war diary for other units to see what code they used for 6" HE.

I have read a few diaries now and see similar codes a lot, however the diaries I have been reading are at brigade or command level, not individual SB level.

 

i thought it may be location details - a target but I can’t find that that tallies with map references tbh and i am not sure on that at all.. 

 

i also discovered that by May 2018 252 had gone up to 6 guns, but I can’t find a reference that precisely dates it but I have written it in my notes. Will revisit the war diary, however my notes say on 9/4/18 252 had 4 guns and was under XB Corps, 45 HAG. 252 moved to 53 Brigade XXII Corps on 22/4/18 and went up to 6 guns so sometime around then i guess.

 

P, S and M

Phosgene. Shrapnel and Mustard maybe?

 

I dont know, without ‘proof’ I am hesitant to take that guess as fact.
