35th Infantry Division (Poland)

35th Infantry Division (Polish: 35. Dywizja Piechoty) was a reserve unit of the Polish Army in the Second Polish Republic. It did not exist in peacetime organization of the army, and was formed between August 31 - September 4, 1939, during the Invasion of Poland.

The division consisted mainly of units which until September 1 manned Fortified Area of Wilno (Obszar Warowny Wilno), and forces of the Border Protection Corps, which guarded northeastern corner of the country. After its formation, the division joined Operational Group Wyszkow.

On September 7, 1939, the division, commanded by Colonel Jaroslaw Szafran, was sent to the area south of Bialystok, where it waited for train transports to move it westwards. On the next day however, Polish Commander in Chief Edward Smigly-Rydz ordered the division to march to the rail junction at Czeremcha, where it boarded trains to Lwow, some 500 kilometers south (see also Battle of Lwow (1939)).

By September 13, 35th Infantry Division was ready to take part in action. On the next day, it manned western line of defence of the city, and on September 15, it attacked the advancing Wehrmacht in Kortumowa Gora and Holosko. Polish attack, in which bayonets were used, halted the Germans, which had to call for artillery support. On September 18, in order to create a link with 10th Motorized Cavalry Brigade, the 35th I.D. attacked along the line Holosko - Brzuchowice. The attack began in the afternoon, and by evening, Polish forces captured complex of a sanatorium along the road to Brzuchowice. Meanwhile, however, 10th Motorized Cavalry Brigade was ordered to break through to Hungary.

On September 19, Polish defenders of Lwow found out about forces of General Kazimierz Sosnkowski, which tried to break into the city from forests in the area of Jaworow. General Wladyslaw Langner immediately ordered the 35th I.D. to attack German positions near Zamarstynow and Holosko. After initial success, Poles were repelled by German tanks, and failed to aid General Sosnkowski. The 35th I.D., which had used up all its ammunition, capitulated in forests near Brzuchowice. Its commandant, Colonel Jaroslaw Szafran, was later captured by the Soviets, and murdered in Katyn Massacre. Furthermore, the NKVD murdered the following officers of the division:
 * Colonel Lucjan Janiszewski, who commanded divisional infantry,
 * Colonel Piotr Parfianowicz of 205th Infantry Regiment,
 * Colonel Edward Koscinski of 206th Infantry Regiment,
 * Colonel Wladyslaw Jozef Mikolajczyk of 207th Infantry Regiment,
 * Colonel Wladyslaw Aleksander Suryn of 33th Light Artillery Regiment
 * Major Doctor Jan Wincenty Krolikiewicz of Sanitary Company,
 * Major Erwin Ludwik Herman Bordolo of Field Court Nr. 33.
