With Byzantium occupied by war with Persia, Avars and Slavs recaptured Roman land south of the Danubian border and a large Slav force advanced on Thessalonica for a second time (after their failure in 586), attempting to capture the city by attack from the sea.
Saint Demetrius was again credited with securing the salvation of his citizens, when the Slav assault ended in chaotic failure with their leader Chatzon taken prisoner.
The anonymous author of the second book of Miracula Sancti Demetrii describes how the saint saved the city encouraging the Greeks by running round the city walls clothed in white, striking fear into the enemy fleet by walking on the sea and appearing on horseback to guard the city gates.
|Aftermath:||The failures of the Slavs to take Thessaloniki propagated the cult of St. Demetrius throughout the Greek world and later became very popular in Slavonic states and also among the crusaders.|
