Greetings all,

On this day, Byzantium Novum commemorates the start of the siege of Dorostolon, on April 23rd in 971 AD:

Russian forces under Svyatoslav I of Kiev had overrun eastern Bulgaria and had occupied the city of Dorostolon. The siege was part of a counteroffensive led by Byzantine forces under Emperor John I Tzimisces. The Russians were able to hold well until the arrival of Byzantine ships, which were able to sweep the city ramparts with Greek Fire. The result was a Byzantine victory.

(The date of the beginning of the Siege is not mentioned in the Wikipedia article, but is found in the book "Byzantine Military Organization on the Danube, 10th-12th Centuries" by Alexandru Madgearu, published in 2013.)
