Hi Prince Edward,
I can only comment on Blenheim 1704 fought in Germany unlike Ramillies 1706, Oudenarde 1708 and Malplaquet 1709 all of which were fought in Flanders.
Huevans was partically correct in that the Dutch govenment did refuse to send their troops outside of Flanders, but after pressure from Churchill did send a small contingent about the same size as the British force.
The totals for the Confederate Armies were 66 Battalions of Infantry, 178 Squadrons of Cavalry and 44 Guns compared to the Franco-Bavarians 84 Battalions of Infantry, 151 Squadrons of Cavalry and 90 Guns.
As at the Battle of Waterloo the Allied forces at Blenheim was made up of allsorts namely British, Austrians, Dutch, Danish, Prussian, Hanoverian, Hesse-Kassel and many other small German states.
The British had 13 Regiments (14 Battalions) of infantry and 7 Regiments (13 Squadrons) of cavalry along with the artillery of Colonel Holcroft Blood.
P.S. Huevans my latest regiments are on my Blenheim OOB thread on page 7 if you care to view.
Kind Regards...........Ray.
