Thanks, carefully filed away.
I found the return for 4 July 1815 and it gives 10 battalions, 14 squadrons and 40 cannon. Total is 15,000 men and 5,100 horses.
Infantry are one company grenadiers, one company chasseurs and four companies fusiliers. Chasseurs and Tirailleurs are four companies each.
It is note that HSH Prince Frederick is the brother of the HM the King of Denmark.
