Events

By place

Byzantine Empire

• March 30 – Balkan Campaign: The Avars lift the siege of the fortress city of Tomis (modern Romania). A Byzantine army under Comentiolus crosses the Balkan Mountains, and marches along the Danube River to Zikidiba.^[1]
• The Avars rout the Byzantine forces of Comentiolus (south of Haemus Mons), and capture Drizipera (Thrace). A large part of their troops are killed by the plague, after many cities are devastated in the Balkan Peninsula.^[1]
• Emperor Maurice pays tribute to the Avars and concludes a treaty with their leader Bayan I, allowing Byzantine expeditions in Wallachia.^[2] He reorganises his army and strengthens the Long Walls (west of Constantinople).^[3]

Europe

• Maurice makes peace with King Agilulf, conceding northern Italy. Pope Gregory I the Great negotiates a truce, ending 30 years of Lombard terror. Agilulf expands the Lombard Kingdom by occupying Sutri and Perugia.

Britain

• Battle of Catraeth: The Gododdin under Mynyddog Mwynfawr, Brythonic king of Hen Ogledd ("The Old North"), defeat the Angles of Bernicia and Deira, at the stronghold of Catraeth in Northern England (approximate date).

Asia

• August 4 – Goguryeo War: Emperor Wéndi orders his youngest son, Yang Liang (assisted by the co-prime minister Gao Jiong), to conquer Goguryeo (Korea) during the rainy season, with a Chinese army (300,000 men).
• The Chinese fleet engages in battle against the Goguryeo fleet (50,000 men) under Admiral Gang Yi-sik, and is destroyed in the Bohai Sea. During the invasion the Sui forces are all defeated, and Yang Liang is forced to retreat.
• King Yeongyang sends an embassy to Daxing; Wéndi accepts a peace agreement with Goguryeo. He claims a hollow victory, as the Sui Dynasty lost nearly 90% of his army and navy during the disastrous campaign.
