Damascus (Moslem Invasion of Syria).
This city was besieged by the Moslems under Khaled in 633, and was defended by a large garrison of Greeks and Romans. The city made an obstinate defence, and the defenders succeeded in sending a demand for succour to Werdan, the general of Heraclius. Werdan's approach drew Khaled away from the place, and as he was retiring he was attacked by the garrison, whom he defeated with enormous loss. He then marched against Werdan, defeated him, and returned to prosecute the siege. After a gallant defence, the city, 70 days later, was taken by storm.
