An armored car, type "Peugeot", from the Belgian Armored Car Corps in Kiev at the shell amaged bell tower of the Military St. Nicholas Monastery, February-March 1918.
Armour (average thickness) of 5 mm. Crew: 4-5 men.
Armament: "Hotchkiss" 37 mm cannon, number of cartridges - minimum 40 or maximum 300. Engine: "Peugeot" power 40-45 hp. Speed on highway: 50 km/h. Range: 140 km.
On one or more Russian armoured cars was with the Belgians, I can agree on that.
One picture from the Barracks in Kiev show such a car together with Belgian armoured cars, shortly before they were destroyed.
The Sviatoshyn Barracks in Kiev, January 1918 - Belgian and Russian armored cars.
If there was a Russian battery (unit) within the Belgian Corps, I do not know - in that case the discussed photo could show the Russian crews. Especially as some of the Russians on the photo do not wear any cockade, perhaps dating the photo to the revolution period - before or just after the Belgians have destroyed the cars?
I only have 2 newer Ukrainian books on the subject:
На периферії війни, Бельгійський бронедивізіон в Україні 1916-1918, Тірі Август, Київ 2010.(At the Periphery of the War, the Belgian Armoured Corps in Ukraine 1916-1918, August Thiry, Kiev, 2010.)
A nice and well illustrated booklet in a series like the English Osprey.
Пілігрими Великої війни. Одіссея бельгійського бронедивізіону у 1915— 1918 роках / А. Тірі. — К.: Темпора, 2010. — 240 с.:(Pilgrims of the Great War. The Odyssey of the Belgian Armoured Coros in 1915 - 1918, A. Thiry, Tempora, 2010. - 240 p.)
but have just ordered "Reizigers door de Grote Oorlog - De odyssee van het Belgische ACM-pantserkorps 1915-1918" par August Thiry & Dirk Van Cleemput, Davidsfonds, Leuven, 2008, which I believe is the book used for translation to the second Ukrainian book and with same photos, printed in 2010. The pictures in the Ukrainian version are terribly reproduced.
The main work on the Corps, I suppose, is: Thiry, Oscar & Marcel, Soldats belges à l'armée russe, Livre de bord d'une auto-blindée belge en Galicie (2ème édition). Liège, 1923, 240 p. ??
The only picture in the two above mentioned books showing Belgians with Russian uniforms with the typical shoulder boards, is a picture showing 4 Belgian deserters, who have taken service with Ataman Semyonov.
ACM deserters, who in Harbin joined the troops of the Siberian Cossack Ataman Semyonov. On the photo: Maurice Kremer (below), Jean Derek (center left), Jules Gachet (inside right) and Eugene Valle (top).
