Her father, a sailor in the Imperial Russian Navy, was killed in the Battle of Sinope in 1853.
She left her home when the war broke out to help take care of wounded Russian soldiers on the battlefield during the Battle of Alma (September 1854).
She set up a nursing station, using vinegar and strips of her clothing to clean and dress the soldiers' wounds.
[citation needed] The Emperor Nicholas I (died 1855) awarded her the Order of St. Vladimir with a gold medal "for diligence".
Asteroid 3321 is named in her memory (3321 Dasha 1975 TZ2 Darya Lavrentyevna Mikhailova).
