Have you seen a whole plate of 75mm rounds for wz.1897 from Polish military manual? If not, I can upload it.Carl Schwamberger wrote: Yes those were of interest. Do you have any other items like this?
You mean, that divisional heavy artillery should be used to strengthen reserve? I don't know, but I think it is desirable for a division to have own artillery component. And the reason, they were weak, was simple lack of moneyAlekBolduin wrote:What were the reasons to have 1 heavy artillery battalion in each infantry division?
Every of this battalion was very weak –there only of 6 guns (3 150-mm howitzers and 3 105-mm cannon) in each. It is not enough to make a good artillery barrage on the battlefield in each case.
Yes, they were semi-AP and AP grenades. All marks of rounds until 1918 were obviously French designs, ALR/2 must have been French as well. Some specifications are on a quoted page.I see in the diagrams of the ammunition there are two types of Granat projectile, shown as Ryo 6 & Ryo 7. I am guessing those were designed for penetrating concrete and similar hardened targets? (...) Perhaps both the Plish and US designs were derived from a earlier French pattern?
Small correction: 8 battalions with 75 mm and 6 with 100 mm.AlekBolduin wrote:In reality, there were 12 light battalion (75 mm), 3 light battalion (100 mm), 16 heavy artillery battalion (105\155-mm) in 8 artillery regiment, 4 heavy battalion (155 mm) and 3 heavy mortars battalions (6-220 mm each).
According to Konstankiewicz, 2003 (referring to Zarzycki) there were mobilized:AlekBolduin wrote:Refine
75 mm : 12 battalions (41, 42,48,50,58,59,62, 64,67,71,75, 81dal)
100-mm : 3 Battalions (65, 68,71,78 dal)
A total of 15 light artillery battalions NWW?
42 dal was changed from 100 mm to 75 mm in May 1939?
There are mixed two things. In a coastal artillery (against shipping) there were 4 x 152 mm Bofors on fixed mounts, 4 x 105 mm (I don't know what guns - probably on ordinary carriages) and 2 x 100 mm Canet on fixed mounts (I'm not counting 75 mm).AlekBolduin wrote: If I remember correctly 4 guns in the coastal artillery, were not 4 105-mm? but 2-152 mm and 2-105 mm, they are considered separately?
I don't know if you mean 10 regular armoured trains, which weren't so funny and appeared quite useful in several cases - or an improvised railway battery of 2 x 75 mm guns of Coastal Land Defence. Poland had no free 152 mm guns on naval mounts to create improvised heavy batteries...AlekBolduin wrote: There were also very funny attempts to make the armored train (instead of railway heavy batteries, for example)
Well, that's the other story. But the question is, if it could be much better in given circumstances?AlekBolduin wrote: And It seems to me that a mobilization plan was not very good….
