He was allocated to a 3-inch mortar unit, attached to HQ Company of the 17th Fusiliers Battalion. After training on the shooting range in practical and tactical skills, he was sent for vehicle training. He completed a course in driving and maintaining military vehicles, and soon became an instructor himself. As well as training officers, he collected deliveries of vehicles for the army. In 1943, following another re-organization, the 6th Lwow Infantry Division was disbanded, and his own 17th Fusiliers Battalion were incorporated into the 5th Borderland Infantry Division. Przeniczka served with the 5th Division throughout the campaign, from Iraq, through Jordan, Palestine and Egypt to Italy. Believing he was working for an Allied victory and an independent post-war Poland, he fought on the rivers Volturno and Rapido. He also took part in the 5th Division's actions against the 'Gustav' and Hitler Line, of fortifications on the Sangro river and on the 'Gothic' line. He served at the battle of Monte Cassino, and the later battles at Senio near Ancona, at Bologna and in Lombardy. After the end of the war, Przeniczka's Division remained in Italy, where he continued his secondary education in Alessano, completing the lower level of the Bacalaureat, whilst at the same time, in May and June 1946, attending an M3 Battery artillery course with the 10th Wolyn Fusiliers Battalion. In 1946 Przeniczka arrived in Britain with the 5th Division, and was sent to Malmesbury Camp, near Bristol. He decided to remain in Britain and enrolled for two years in the Polish Resettlement Corps. This was a temporary arrangement, after which he was allocated a permanent place to stay. After de-mobilisation in 1948, he began working in Warwick and later in Leamington Spa. In 1957 he married Bogumila Bozena Lapinska, with whom he had two children, Barbara and Edward. In 1961, together with a group of patriots, he founded the Polish Centre in Leamington Spa, an organisation serving all members of the local Polish community. At the inaugural AGM he was elected treasurer. The organisation gave generous financial assistance to the Polish Government in Exile, the Polish Cultural Centre (POSK) and the local Polish language school. For over fifty years Przeniczka was a permanent member, and from 1985 to 2015 he served as treasurer and chief accountant.
