In 1912 , Petrović 's mother died . With the outbreak of the Balkan Wars soon after , Petrović volunteered to become a nurse and was awarded a Medal for Bravery , Order of St. Sava and an Order of the Red Cross for her efforts . She continued nursing Serbian soldiers until 1913 , when she contracted typhus and cholera . In the later years of her life , she had little time to paint and produced only a few canvases , including her post-impressionist masterpiece '' The Valjevo Hospital '' ( ) . Professor Andrew Wachtel praised the painting for its " bold brushstrokes and bright colours " and its depiction of " a series of white tents against an expressionistic , almost Fauvist , landscape of green , orange , and red . " Petrović found herself in Italy when Austria-Hungary declared war on Serbia in July 1914 . She immediately returned to Belgrade to assist the Serbian Army . Having volunteered to work as a nurse in Valjevo , she died of typhoid fever on 3 April 1915 in the same hospital depicted in '' The Valjevo Hospital '' . Following her death , her likeness has been depicted on the Serbian 200 dinar banknote
