On October 9, 1920, the team of General Lucjan Żeligowski occupied Vilnius and continued the attack in the west and northwest direction. On November 17, the attack on Ukmergė, launched by the Polish army, stalled. They managed to occupy Širvintos and Giedraičiai. The Lithuanian army started the attack in the night from November 20 to 21. Part of the military forces attacked Giedraičiai. The 2nd infantry regiment is from Želva, and the 9th infantry regiment is from Videniškiai. As the Lithuanians attacked in the direction of Giedraičiai, heavy fighting took place in the vicinity of Giedraičiai near Šiupieniai (Šiupieniai manor) and the farm buildings of Seirūnai manor. Also in the Bekupė manor - 4 km northwest of Giedraičiai. Polish soldiers remained on the heights of the front line near Giedraičiai, supported by artillery fire in the Martiniškiai Manor. Here the Poles resisted the Lithuanians for the last time. Later, units of the Lithuanian army drove the Poles out of their occupied positions and entered Giedraičiai. The place of the Battle of Giedraičiai is marked and the memory is given meaning by a symbolic cannon.
