Y.R. 699 It is believed that the Usipetes and the Tenchteri, German tribes, with 800 of their own horse, put to flight about 5000 of Caesar’s horse. When they sent ambassadors to Caesar he held them as prisoners and made an attack on them, and took them so completely by surprise that 400,000 of them were cut to pieces. One writer says that Cato in the Roman Senate proposed that Caesar should be surrendered to the barbarians for this deed of blood perpetrated while negotiations were pending. But Caesar in his own diary says that when the Usipetes and Tenchteri were ordered to go back forthwith to their former homes, they replied that they had sent ambassadors to the Suevi, who had driven them away, and that they were waiting for their answer; that while these negotiations were pending, they set upon his men with 800 of their horse, and by the suddenness of the attack put to flight his 5000; and that when they sent another embassy to explain this violation of good faith he suspected a similar deception, and made his attack before B.C.55 giving his answer.Caesar’s iv. 1-5; Plutarch, 22. The latter repeats Cato’s proposal that Caesar should be surrendered to the barbarians for his breach of faith.
