About Bolesław Zajączkowski

Lived 1891 – 1920 (aged 28–29). Bolesław Zajączkowski was a lawyer.

Capt. Bolesław Zajączkowski (1891, in Kraków – August 17, 1920, in Zadwórze) was a Polish lawyer and reserve officer of the Polish Army.

Polish-Ukrainian War A former reserve NCO of the Austro-Hungarian Army, he volunteered for the Polish forces fighting in the battle of Lwów in the Polish-Ukrainian War. During the fights for that city against the forces of the West Ukrainian People's Republic he commanded a machine gun post at the so-called Execution Hill , a scene of particularly heavy fights.

After the successful defense of the city, he returned to civilian life only to rejoin the Polish Army after the outbreak of the Polish-Soviet War.

Polish-Soviet War During the Budennyi's assault on Lwów he was chosen as a commander of a volunteer battalion of roughly 330 men, mostly pupils and students.

Battle of Zadwórze All but 12 men of that volunteer battalion perished in an 11-hours long battle of Zadwórze. For entire day, August 17, the unit under his command withheld repeated attack by an entire cavalry division. After their defenses were finally broken, Zajączkowski committed suicide not to fall into enemy hands. For his merits he was posthumously promoted to the rank of Major and awarded with Virtuti Militari medal. After the war his body was one of five to be exhumed, identified and buried with military honors at the Lwów Eaglets' Cemetery in Lwów. The battle was sometimes called "The Polish Battle of Thermopylae".
