Dou Xian vs Gaius Terentius Varro

Dou Xian served as regent for the young Emperor He of Han after Emperor Zhang's death. He dominated the court, appointing his relatives to key positions. His regency was marked by military success but also by corruption and nepotism.

Dou Xian led a Han expedition against the Northern Xiongnu at the Battle of Ikh Bayan. His forces killed over 13,000 Xiongnu and captured 200,000 livestock. The victory shattered the Northern Xiongnu confederation, ending their threat to the Han dynasty.

After the Battle of Ikh Bayan, Dou Xian erected a stone inscription on Mount Yanran (modern-day Mongolia) to commemorate the victory. The inscription, written by Ban Gu, celebrated the Han triumph and marked the furthest extent of Han military reach.

Emperor He, with the help of eunuchs, orchestrated a coup against Dou Xian in 92 AD. Dou Xian was stripped of his titles and forced to commit suicide. His family and supporters were purged, ending the Dou clan's dominance.

Varro, as consul, commanded the Roman army against Hannibal at Cannae. The Romans suffered a catastrophic defeat with tens of thousands killed. Varro survived and fled the battlefield, but was not punished by the Senate.

After Cannae, Varro was given command of the legions in Picenum and later in Gaul. He served honorably, raising new troops and defending Roman territories against Carthaginian incursions.

Varro served as proconsul in Etruria, where he conducted military operations against Hannibal's forces. He successfully prevented Carthaginian raids and maintained Roman control over the region.
