The Fort of St. Elmo ultimately fell on the very eve of the feast of St. John the Baptist, the patron saint of the Order, in a moment of dark irony. The Knights had to move to Fort of St. Angelo in Birgu and hold out until the end there. After some spectacular victories in September, as well as the arrival of a relief force from Sicily, the Knights finally prevailed, and the siege was lifted. On that day, all the church bells rung throughout the island, and, incidentally, Birgu was renamed into Vittoriosa (the Victorious One).
