February 24, 1863 Piotrowiczowa was deeply affected by news about the defeats, arrests, and imprisonments of insurrectionary troops and decided to support the fighting in person. Together with her husband and some of the servants from the manor farm near
Łódź, she joined Józef Dworzaczek's troops in the area. She cut her hair and donned an insurrectionary czamara (men's long-sleeved, fitted, braided outer garment, fastened at the neck, worn by Polish noblemen during the 17th-19th century). The troop consisted of several hundred people, mostly scythe-bearing peasant recruits, several dozen riflemen, and less than 50
uhlan. In the beginning, Piotrowiczowa was on auxiliary duty, collecting money for the troop and buying, weapons, food, and supplies. When the military situation deteriorated, she declared her intention of taking on front-line duty. Piotrowiczowa's troop was tracked down by Russian garrisons stationed in
Piotrków Trybunalski and
Łęczyca. Because of mistakes in commending and because of an ostentatious march in the towns of the
Łódź area, there was an unnecessary unmasking of the troop. It eliminated a surprise element, which is indispensable under
guerrilla warfare conditions. On 24 February 1863, as the insurgents camped on the edge of the forest near the village of Dobra, the
Russians took them by surprise. Dworzaczek, a doctor, had neglected to post a guard and conduct reconnaissance. The troop was encircled and forced to accept a defensive battle. The battle started around midday and lasted until 5:00 p.m. From the beginning, it was unfavorable for the Polish side. The insurgents repulsed two
Cossack’s attacks but during the third one, they defended themselves in a chaotic way. Some insurgents did not manage to slip out of the encirclement. Piotrowiczowa fought to the very end, instead of escaping from the battlefield. She rejected the suggestion of surrender, given to her by Russian officers, because she recognized that such an attitude was incompatible with the dignity and honor of a Pole. Together with a group of young people she bravely defended the troop flag donated by
Łódź women. Encircled by
Cossack, she killed one, wounded another one, and killed the horse under yet another. She defended herself with a revolver and a scythe. She died from being hacked by the
Cossack. The
Cossack tortured the dead Piotrowiczowa's body. Her body was pricked with piqués and sabres. Her clothing, all in shreds and in blood, was preserved by her family as a relic. The tragedy was enhanced by the fact that Piotrowiczowa was pregnant, later it turned out that she was bearing twins. After the battle, the Russians demanded ransom for releasing her body and for allowing it to be brought to the manor house. In the battle of Dobra three more women were also killed: Weronika Wojciechowska (aged 19) – a servant from
Byszewy, Antonina Wilczyńska (aged 20) – a worker from
Łódź and Katarzyna, whose surname remains unknown, fighting at Piotrowiczowa's side. In the
Battle of Dobra, about 70 insurgents were killed and twice as many were wounded. About 80 insurgents were captured. Some of them were shot, others were sentenced to penal servitude. == Funeral==
