The outbreak of World War I found Rodziewiczówna in Warsaw. She took part in the organization of a military hospital; she also helped organize cheap kitchens for intelligentsia and academic assistance. In 1915 she returned to Hruszowa for some time, taking care of the refugees she had tried to keep there. In the years 1919–1920 she initiated a number of social activities in the area of Hruszowa, establishing an agricultural circle, building a steam room, and rebuilding the cheder in Antopol. During the Polish-Bolshevik war, she was in Warsaw, where she was the secretary of the Main Committee of the Polish Red Cross and was appointed commander of the Women's Volunteer Committee for the Relief of Lviv in the city of Warsaw. For her activity in this field, she was awarded the Medal of Honor, which was accompanied by a diploma signed by General Tadeusz Rozwadowski. After the end of war, she returned to Hruszowa. Years later, Rodziewiczówna considered this diploma the most important memento of her activity.
