Chanyu Huhanye came to the Wuyuan frontier pass and asked to attend the audience of the following year's first month; Han received him as a guest and placed his rank above the vassal kings. (Book of Han (Hanshu), Imperial Annals 漢書卷008 宣帝甘露二年十二月)
Huhanye came to Chang'an for audience: at the Wei Bridge they shouted 'long life', and a banquet was held at Jianzhang Palace; he called himself a subject but was not to be called by his name. (Book of Han (Hanshu), Imperial Annals 漢書卷008 宣帝甘露三年正月)
The chanyu returned home and settled at the Guanglu city south of the desert; Han escorted him and supplied grain to the northern frontier, while Zhizhi Chanyu fled far away. (Book of Han (Hanshu), Imperial Annals 漢書卷008 宣帝甘露三年二月)
The Xiongnu Chanyu Huhanye came to court and called himself a vassal, but was not to be addressed by his personal name. He received generous gifts of court robes, clothing, a golden swan, a sword, a bow, and a peace-pledge chariot. (Zizhi Tongjian (Comprehensive Mirror) 資治通鑑 卷027 (원문 단락 #2093, -51년))
As the Carnutes abandoned their towns and scattered, Caesar, avoiding the harsh weather, quartered soldiers in private houses at Cenabum, and sent cavalry and auxiliaries in all directions following the enemy's traces. (Caesar, Commentaries on the Gallic War 8.5)
When Caesar camped in the land of the Bellovaci, they gathered an alliance of the Ambiani, Caleti and others under Correus on high ground and faced him; Caesar fortified his camp with a 12-foot rampart, two ditches and towers. (Caesar, Commentaries on the Gallic War 8.7–8.10)
Correus set an ambush with 6,000 infantry and 1,000 cavalry on the route bringing in supplies; from prisoners' information Caesar saw through it, went out with more legions, and a battle broke out in which Correus fell. (Caesar, Commentaries on the Gallic War 8.17–8.19)
The defeated Bellovaci sent envoys surrendering and handing over hostages, but Commius alone fled to the Germans, distrusting them because Labienus had tried to assassinate him. (Caesar, Commentaries on the Gallic War 8.21–8.23)
With the most warlike tribe broken, Caesar divided his army: he sent Fabius far away and Labienus to punish the Treveri, while he himself devastated the land of the Eburones with sword, fire and plunder. (Caesar, Commentaries on the Gallic War 8.24)
Caninius, hearing that Duratius at Limonum in the land of the Pictones was besieged by the Andes leader Dumnacus, set out to rescue him; Dumnacus instead tried to attack Caninius's camp. (Caesar, Commentaries on the Gallic War 8.26)
When Fabius came to rescue Duratius, Dumnacus withdrew to cross the Loire; Fabius's cavalry commander Varus pursued and engaged, and when legions appeared the enemy broke and was slaughtered in great numbers. (Caesar, Commentaries on the Gallic War 8.27–8.28)
Drapes of the Senones and Lucterius of the Cadurci took Uxellodunum (Lucterius's former domain) in the land of the Cadurci and resisted; Caninius tightened the siege with three camps. (Caesar, Commentaries on the Gallic War 8.32)
Leaving Antonius in the land of the Bellovaci, Caesar personally toured many tribes collecting hostages; the Carnutes handed over Gutuatrus, ringleader of the revolt, and he was executed. (Caesar, Commentaries on the Gallic War 8.38)
Caesar arrived at Uxellodunum, saw it already surrounded, and decided to cut off its water supply, since the town had plenty of grain: a river wraps around the mountain and there was a spring nearby. (Caesar, Commentaries on the Gallic War 8.40)
