The article discusses selected issues concerning mobilisation of the Polish Army of the Second Polish Republic, with special recognition to the role of the Wadowice garrison and the participation of the residents of the region in those plans. Among other issues, the differences in the regional impact of individual departments of the armed forces operating in Wadowice as well as the diversity in trainings for the needs of various types of military and paramilitary services were described. Wadowice was an infantry garrison, but in terms of preparation, the cavalry as well as groups of women for educational services and groups of men for sanitation services were trained here. In the above mentioned areas the trainings conducted by Wadowice garrison involved residents of the Wadowice district, Myslenice district and shortly existing Makow and Oswiecim districts. In terms of administration and mobilisation of reserves, District Draft Office (Powiatowa Komenda Uzupelnień) later Wadowice Region Draft Office (Komenda Rejonu Uzupelnień Wadowice) involved the area of Wadowice district and Chrzanow district. The article indicates the role, which for the garrison of Wadowice was envisaged in further mobilisation plans created in the period 1920-1939. The article further indicates additional burdens that increased the mobilisation duties for the 12 Infantry Regiment in being a part of an implemented plan during the 30s program of modernisation and expansion of the armed forces. Against the background of the so-called mobilisation network (as of January 1939) the article discusses formations to which inhabitants of district Wadowice were mobilised most often in August and September 1939. Based on an example of court documents relating to the soldiers fallen(killed) or missing in the campaign the elements supporting evidence for the use of the above mentioned mobilisation network were pointed out. There is also an indication that the likelihood that in the last months before the outbreak of World War II, changes to this network had been made, as a result of which the further formations were replenished by larger groups of reservists from the area of operation of Wadowice Region Draft Office (KRU Wadowice).
