he chaired the Lithuanian delegation which negotiated and signed the Suwałki Agreement with Poland. When Poland staged the Żeligowski's Mutiny and captured Vilnius, he was sent to Latvia in November in an effort to conclude a military alliance against Poland and Żeligowski. Latvia rejected a direct military alliance but agreed to support Lithuania by providing military specialists and military equipment. In early 1921, he organized the Higher Officers' Courses for senior officers of the Lithuanian Army and became their first chief. At the same time, he again became Chief of the General Staff on 13 April 1921. Carrying out both duties proved to be difficult and he resigned from the Higher Officers' Courses in July 1921. He was a member of a Lithuanian delegation sent to the League of Nations in Geneva to negotiate with Poland regarding Vilnius Region in September 1921. However, he became ill on the way and spend about a month recovering. In August 1922, Kazys Ladiga submitted a complaint that a "Russian monarchist" party was active in the Lithuanian military and that Katche was part of it. Ladiga was punished with 7-day arrest for false report but Katche resigned on 7 October 1922 (officially, due to health reasons). Katche retired to Biržai, the birthplace of his wife Berta Jansonaitė. He worked at a bank and as a director of a factory. He died in Biržai on 10 June 1933. His funeral was a public affair and included a flyby of military airplanes. His grave stone disappeared during the Soviet period and the exact location of his burial has long been debated. In 2019, the government of Lithuania declared his grave a state protected monument and a new grave stone was unveiled on 23 November 2019.
