The fear thus inspired variously affected his own troops and the enemy. Our men gained fresh valour; the barbarians felt their pride broken. The Frisians, who had been hostile or disloyal since the revolt which had been begun by the defeat of Lucius Apronius, gave hostages and settled down on territories marked out by Corbulo, who, at the same time, gave them a senate, magistrates, and a constitution. That they might not throw off their obedience, he built a fort among them, while he sent envoys to invite the Greater Chauci to submission and to destroy Gannascus by stratagem. This stealthy attempt on the life of a deserter and a traitor was not unsuccessful, nor was it anything ignoble. Yet the Chauci were violently roused by the man's death, and Corbulo was now sowing the seeds of another revolt, thus getting a reputation which many liked, but of which many thought ill. "Why," men asked, "was he irritating the foe? His disasters will fall on the State. If he is successful, so famous a hero will be a danger to peace, and a formidable subject for a timid emperor." Claudius accordingly forbade fresh attacks on Germany, so emphatically as to order the garrisons to be withdrawn to the left bank of the Rhine.
