The outbreak of World War II disrupted the activities of the Orchestra, which was reestablished in October 1948. During the Bosnian War, the Orchestra again suffered disruption. During the Siege of Sarajevo, seven members of the Sarajevo Philharmonic Orchestra were killed and twelve were wounded. The archive of musical scores was damaged and many instruments were destroyed, damaged or lost. During the war, however, the Sarajevo Philharmonic Orchestra continued its work and performed 60 concerts, 20 of them abroad. The rehearsals were performed in hard winter conditions, in basements, and without heating and only by candlelight.
