The Zaolzie Campaign (Polish: Kampania Zaolzie, Czech: Těšínské kampaň) was a military conflict fought from October 8 to October 13, 1938 between the Republic of Czechoslovakia and the Second Polish Republic over the disputed areas of Cieszyn Silesia (Śląsk Cieszyński/Těšínské Slezsko), Orava Territory (Orawa/Orava) and Spiš (Spisz/Spiš). Though it is contemporaneous with the German invasion, the Polish military operation was a result of a decision of the Polish government, and both Germany and Hungary was not consulted when the operations begun.
