As Count and General of the Artillery (Generalfeldzeugmeister) he sided with
Prussia during the
Seven Years' War. He distinguished himself at the head of the allied artillery during the
Battle of Minden and was rewarded with the overall command of the allied artillery.
Portugal In 1762, at the request of the
Marquis of Pombal (the
Portuguese Secretary of State) he led, as
Generalissimus, the allied troops in Portugal against the
Spanish invasion. William conducted a brilliant defensive campaign of marches and counter-marches, so that the enemy, although it had a three-to-one superiority in numbers, always encountered defenders in a good position and never dared to risk an all-out attack. At the request of Pombal, Lippe stayed on for a year after the
peace agreement of 1763. He was also an influential military theorist and an advocate of defensive warfare. One of his best-known slogans is: "Kein anderer als der Defensivkrieg ist rechtmäßig!" ("Only defensive warfare is justified!") He died at
Wölpinghausen and was succeeded by his cousin the count of
Lippe-Alverdissen,
Philipp II. Ernst. As one of the greatest figures in
German history, he is commemorated by a bust in the
Walhalla temple. ==Family==
