Size of 1915/1918 Triangular German Infantry Division

[Der Alte Fritz]

How many men, horses, vehicles, guns, MG, etc were in the 1917 German Infantry Division when it was reorganized on the 3 Regiment, 3 Battalion basis?

[Latze]

According to Ellis and Cox "The World War 1 Databook", London 2001, p. 232:

13.000 men
219 lmg
130 mg (included the attached marksmen detachment)
76 mortars
36 field guns/light howitzers
12 heavy guns
470 horsed vehicles
2100 horses
10 motor transports

That is excellent, my original source, the Handbook of the German Army at War (Nov 1918) was less accurate being an intelligence document and did not give the information about horses, vehicles, etc.
