General Louis Botha. Carton de Wiart was appointed a Companion of the Order of the Bath in the 1919 King's Birthday Honours List. After a brief period, he replaced General Botha in the mission to Poland. Poland desperately needed support, as it was engaged with Bolshevik Russia in the Polish-Soviet War, the Ukrainians in the Polish-Ukrainian War, the Lithuanians in the Polish-Lithuanian War, and the Czechs in the Czech-Polish border conflicts. There he met Ignacy Jan Paderewski, the pianist and premier, Marshal Józef Piłsudski, the Chief of State and military commander, and General Maxime Weygand, head of the French military mission in mid-1920. One of his tasks soon after his arrival was to attempt to make peace between the Poles and the Ukrainian nationalists under Simon Petlyura. The Ukrainians were besieging the city of Lwów (; ). The discussions were unsuccessful. From there he went on to Paris to report on Polish conditions to the British Prime Minister, David Lloyd George and to General Sir Henry Wilson. Lloyd George was not sympathetic to Poland and, much to Carton de Wiart's annoyance, Britain sent next to no military supplies. Then he went back to Poland and many more front line adventures, this time in the Bolshevik zone, where the situation was grave and Warsaw threatened. During this time he had significant interaction with the nuntius (dean of the Vatican diplomatic corps) Cardinal Achille Ratti, later Pius XI, who wanted Carton de Wiart's advice as to whether to evacuate the diplomatic corps from Warsaw. The diplomats moved to Poznań, but the Italians remained in Warsaw along with Ratti. From all these affairs, Carton de Wiart developed a sympathy with the Poles and supported their claims to eastern Galicia. This caused disagreement with Lloyd George at their next meeting, but was appreciated by the Poles. At one time during his Warsaw stay he was a second in a duel between Polish members of the Mysliwski Club, the other second being Baron Carl Gustaf Emil Mannerheim, later commander-in-chief of Finnish armies in World War II and President of Finland. Norman Davies reports that he was "compromised in a gun-running operation from Budapest using stolen wagon-lits". He became close to the Polish leader, Marshal Piłsudski. After an aircraft crash occasioning a brief period in Lithuanian captivity, he went back to England to report, this time to the Secretary of State for War, Winston Churchill. He
