Greetings all,

On this day, we commemorate with sadness the battle of Pegae which was fought between Byzantine and Bulgarian forces on March 11th in 921 AD:

https://en.wikipedia.org/wiki/Battle_of_Pegae

Pegae meant  "the spring" and was named after the nearby Church of St. Mary of the Spring. The Bulgarian forces held the high ground and charged into the Byzantine front line with irresistible momentum. This initial attack collapsed the Byzantine front lines. The Byzantine commanders fled as they were unable to untangle the lines or regroup their forces and the battle was a complete rout and Byzantine defeat. 

-Marcus Cassius Julianus
