This gentleman helped Wellington meet his goal of defeating Napoleon (from Wikipedia):
Hans Ernst Karl, Graf von Zieten (5 March 1770 – 3 May 1848) was an officer in the Prussian Army during the Napoleonic Wars.
During the Waterloo Campaign of 1815, Lieutenant-General von Zieten commanded the Prussian I Corps. The corps fought a holding action against the French on 15 June, and was heavily engaged against the French the next day at the Battle of Ligny, and then again two days later on June 18 at the Battle of Waterloo.
On 1 July, Zieten’s I Corps participated in the Battle of Issy just outside the walls of Paris. At the end of the campaign on 7 July, his corps was granted the honour of being the first major Coalition force to enter Paris.
King Frederick William III of Prussia granted Zieten the title of Graf, or count, on 3 September 1817. At the age of 69, he was promoted to Generalfeldmarschall on 9 September 1839. Zieten died in Warmbrunn.

Well done, Denise. Great theme, excellent posts.
Thanks, Martha. This past week suffered due to being on the road, but I did put much effort into the posts before I left. I enjoyed revisiting so many good musicals and enjoyed being reminded what I have not seen! Cheers, D
As your theme, Martha, was musicals! 😉
