Carus vs King Helu of Wu

Carus launched a campaign against the Sarmatians along the Danube frontier. He defeated them in battle and forced them to sue for peace. This victory secured the Danube border and allowed him to turn his attention to the east.

Carus was proclaimed emperor by the legions in Pannonia after the assassination of Probus. He was a respected military commander and senator. His accession marked a brief period of stability and renewed military expansion.

Carus led a major invasion of the Sassanid Persian Empire. He advanced through Mesopotamia, capturing the cities of Seleucia and Ctesiphon, the Persian capital. This campaign restored Roman prestige after years of defeats by the Persians.

Carus died suddenly during his Persian campaign, reportedly struck by lightning in his tent. Some sources suggest he was assassinated. His death ended the campaign, and his son Numerian succeeded him, but the empire soon fell into further turmoil.

King Helu of Wu appointed Sun Tzu as his general after Sun Tzu demonstrated his military discipline by executing two of the king's favored concubines. This decision brought Sun Tzu's strategic expertise to the Wu military, leading to successful campaigns.

King Helu led Wu forces to a decisive victory over the Chu state at Boju. Using Sun Tzu's tactics, Wu captured the Chu capital Ying, forcing King Zhao of Chu to flee. This victory established Wu as a major power in the Spring and Autumn period.

King Helu invaded the Yue state but was defeated at the Battle of Zuili. He was wounded by an arrow during the battle and died shortly after. His death led to his son Fuchai ascending the throne, who later sought revenge against Yue.
