I was introduced to Eugen the same way as perhaps most history enthusiasts in the Anglophone world--as Marlborough's great ally in the War of Spanish Succession. Also, Napoleon had given him favorable mention, placing him in the same pantheon as Alexander, Hannibal, Gustavus Adolphus, Frederick the Great and others.
Setting out to find out what more I could about Eugen, I found Henderson's biography, and little else. As one reviewer has already pointed out, Henderson focuses broadly on Eugen's whole life and does not give perceptive analysis concerning Eugen's military exploits. Hopefully someday a military historian will write a book on Eugen's generalship, or such an existing work will be translated into English.
Eugen's early years near the court of Louis XIV, his rejection by the Sun King in wanting to join his army, and subsequent service with the Hapsburgs is the stuff of a great historical novel. One of the great what-ifs of that era must be what if Louis would have said yes to Eugen.
In the employ of the Hapsburgs, Eugen worked on interior lines of sorts against the Ottoman's expansion on one side, and Louis XIV's ambitions on the other. His status as a great independent commander was secured by the rout of the Turks at Zenta in 1697. Later, with Marlborough, he helped frustrate Louis' designs at the battles of Blenheim, Oudenarde and Malplaquet.
Not just a great general, Eugen also had intense interests in architecture, art and books. He built Belvedere, the baroque palace in Vienna, and possessed thousands of works of art and books. It is a pity that at his death he was intestate, and never having married, his estate went to a niece he barely knew and who had little affection for her uncle. Even if Eugen wasn't into the ladies, as some have suggested, he should have bitten the bullet and produced an heir, as most like-minded aristocrats were wont to do.
