The youngest, Joachim,born on 17 Dec 1890 in Berlin. He died on 18 Jul 1920 in Potsdam. He was also the subject of homosexual rumors. He was married unhappily to Princess Marie of Anhalt. They had one child, Karl Franz Joseph who would marry his step-grandmother's daughter. He was apparently not as strong as the other boys and his mother worried about him. Joachim appears to have been an impatient boy. He served in WWI as a calvary officer. He was woulded in the battle in the Masurian Lake District of East Prussia. He married Marie of Anhalt in 1916. After the Armistace in 1918, Joachim visited his father at Doorn. It was not a happy reunion. The former Kaiser was unhappy with his sons' behavior, including Joachim's gambling. Joachim eventually returned to Germany. He found it difficult adjusting to his reduced circumstances. His wife left him. He shot himself in 1920 at a hunting lodge near Potsdam. Considered his mother's favorite, it was thought this hastened her demise. Marie of Anhalt later adopted as a "son" who calls himself Prince of Anhalt and who is married to Zsa-Zsa Gabor.
