On 2 November 1916, Marie's youngest son, Prince Mircea, who had been sick with typhoid fever, died at Buftea. Marie was distraught and wrote in her journal: "Can anything ever be the same?" After Bucharest fell to Austrian troops, the royal court was transferred to Iași, capital of the Moldavia region, in December 1916. There, she continued to act as a nurse in military hospitals. Daily, Marie would dress as a nurse and go to the train station, where she would receive more injured soldiers; then she would transport them to hospital.
