During World War I, Romanian Scouts were very active in defense activities. Ecaterina Teodoroiu guided a patrol of Scouts and Guides and was employed as a nurse, before joining the Romanian Army and dying a heroine. Many Scouts who helped the transporting of the wounded were killed during the air attacks. On September 29, 1916, Baden-Powell sent a message expressing regret to the Scouts for the death of their fellows. At the end of the war, the Boy Scouts marched in the front of the Victory Train, under the Triumphal Arch in Bucharest.
