Johann Wilhelm, Elector Palatine died in June 1717. Anna Maria Luisa returned home in October 1717, bringing with her vast treasures. Cosimo created his elder son's widow, Violante of Bavaria, Governess of Siena as to clearly define her precedence. That did not stop the two ladies from quarrelling, as was his intention. Cosimo discontinued hunting following an accident in January 1717. He accidentally shot, and killed, a man. He was so distraught, that he wished to be tried by the Knights of the Order of Saint Stephen. The state of the Grand Duchy reflected the decay of its ruler; in a 1718 military review, the army numbered less than 3000 men, some of whom were infirm, and aged 70. The navy composed of three galleys, and the crew 198. In September 1721, the Grand Duchess died; instead of willing her possessions to her children, as prescribed by the 1674 agreement; they went to the Princess of Epinoy.
