their country had entered the war, Ferdinand and Marie dismissed their German servants, who could only remain in their employ as "war prisoners" of sorts. Early on during the war, Marie was involved in aiding the Romanian Red Cross and visited hospitals daily. During the first month of hostilities, Romania fought no less than nine battles; some, such as the Battle of Turtucaia, took place on its own soil. 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. After the conclusion of the Russian Revolution in early November 1917 and the victory of the Bolsheviks, Romania became, in the words of diplomat Frank Rattigan, "an island surrounded on all sides by the enemy, with no hope of assistance from the Allies". Soon afterwards, Ferdinand signed the Treaty of Focșani, on 9 December 1917. Marie considered the treaty perilous, while Brătianu and Știrbey believed it was a necessary measure for obtaining more time. Later turns of events would prove Marie to have assumed correctly. In 1918, Marie vehemently opposed the signing of the Treaty of Bucharest, giving rise to her description as "truly the only man in Romania". The Armistice with Germany (11 November 1918) put an end to fighting in Europe and, thus, to the war. In the tenth century, the Principality of Hungary had begun conquering Transylvania, which Hungarians had fully occupied by around 1200. The idea of a "Greater Romania" had existed in the minds of Romanians in Transylvania for some time and Brătianu had actively supported the concept before the war. In 1918, both Bessarabia and Bukovina voted for union with Romania. An assembly took place in the ancient city of Alba Iulia on 1 December 1918, where Vasile Goldiș read the resolution for the union of Transylvania with the Old Kingdom. This document, supported by Romanian as well as Saxon deputies, established a High National Romanian Council () for the province's temporary administration.
