Recently, the gang at Small Arms of the World posted a World War II vintage German language weapons manual (subscription required) that focused mostly on German service submachine guns.1 The manual was developed by a retired officer, Colonel Schmitt. Col. Schmitt was a prolific author of small arms and military manuals (of the sort that might be popular with earnest young soldiers, and youth looking forward to military service). He was also the editor of a range of war maps. His materials appeared though the publishing house of R. Eisenschmidt, located on Mittelstraße 18 in Berlin NW7.
At first we thought so the introductory material would be useful in an ongoing research project on early submachineguns. Even though this is not a primary source on early SMG’s, it’s an earlier secondary source than many of the documents we’ve been working with. So we thought it might be authoritative. Indeed, it starts off making sense, and it’s chock full of interesting material; but there are enough errors to give us considerable pause. Let’s start with the sensible bit (our translation):
General Information for all MPs Found in Units
The MP is a weapon that is particularly suited for close combat.
Due to the weapon’s stability in automatic fire, a tight grouping of bursts of fire is enabled. Small targets can be engaged with good success at distances to 100 meters, and larger targets up to 200 m. Beyond 200 m distance, ammunition expenditure is unlikely to meet with success.
The low number of cartridges that can be carried by troopers, and the heavy ammunition demand in the front line, constrain the employment of the MP to snap missions at short distance and to close combat.
This is good, interesting information. But can we trust it, about the MPs that were carried in the first world war? Certainly, we want to trust it; Colonel Schmitt must surely know what he’s talking about, mustn’t he?
Very soon, we come upon information that turns out to be less than trustworthy, on the same page of this same document:
The following models are currently employed:
- MP 18I (System Bergmann)
- MP 28II (System Schmeisser),
- MP Erma (System Vollmer),
- MP 38 (smooth receiver),
- MP 40 (receiver with flutes), and
- MP 34 (with mounted bayonet M.95).
The MPs only fire the pistol cartridge 08 (cal. 9 mm) except the MP 34 which to date only fires the Steyr cartridge (9mm). 2
(The unusual use of superscript Roman numerals in the MP 18 and MP 28 designators is like that in Schmitt’s original).
Now, the world of early German MPs is grey enough that we can let the distinction between “System Bergmann” and “System Schmeisser” slide. (As we understand it, Schmeisser was the primary designer of both, and the magazine housings were generally marked with “Schmeissers Patent” for the double-column, single-feed magazine, but the guns were made by Bergmann).
But notice, that the good Colonel has the MP.38 and MP.40 exactly backwards. While there were many other changes between the 38 and 40, and additional running changes in production (like the two-part “safety” bolt-handle, sometimes called an MP.40 feature but actually introduced as a running change in the MP.38), one of the key improvements in the MP.40 was the lack of fluting, which allowed more rapid, less costly manufacture.
It wasn’t just a single error, for if you skip ahead to where Schmitt treats the MP.38 and .40 (as a single section of his book, which makes perfect sense given the guns’ near-identical nature)3, he makes the same error:
The footnote (with asterisk) refers to a reference to the receiver, higher on the page, and reads, “On the MP.38, the receiver is smooth; on the MP.40 it is provided with flutes.”
We assume that Colonel Schmitt was truly an expert, and that he took good care with his manuals, which he knew would be bought and read by Wehrmacht troopers and those soon to be Wehrmacht men. But here’s an example of a mistake he made on a simple thing. It reinforces the importance or critical reading of sources, even of period sources (and even primary sources).
It’s also important to weigh the expertise of a source with the left and right limits of his knowledge… his expertise’s “range fan,” if you will. Combat soldiers may have their heads full of mistaken ideas about the development and manufacture of their weapons, and design engineers, contract managers, and hands-on manufacturing workers may be in the dark about how their products are employed in the field.
And everybody’s human, and makes mistakes. Nicht wahr, Oberst Schmitt?
This is one place where 21st Century scholarship has an edge. If poor old Schmitt made an error, by the time he heard about it R. Eisenschmidt could have printed 20,000 copies of the booklet with the error. If a blogger makes an error, he’s called out on it in the comments forthwith (don’t ask us how we know this).
