D. 14.--The news spread like wild-fire, and the Romans found themselves threatened in their very camp (whence they had taken care not to stir since their check) by a mighty host both of horse and footmen. Caesar was compelled to fight, the legions were drawn up with their backs to the rampart, that the hostile cavalry might not take them in rear, and, after a long hand-to-hand struggle, the Roman charge once more proved irresistible. The Britons turned their backs and fled; this time cut up, in their retreat, by a small body of thirty Gallic horsemen whom Commius had brought over as his escort, and who had shared his captivity and release. So weak a force could, of course, inflict no serious loss upon the enemy, but, before returning to the camp, they made a destructive raid through the neighbouring farms and villages, "wasting all with fire and sword far and wide." D. 15.--That same day came fresh envoys to treat for peace. They were now required to furnish twice as many hostages as before; but Caesar could not wait to receive them. They must be sent after him to the Continent. His position had become utterly untenable; the equinoctial gales might any day begin; and he was only too glad to find wind and weather serve that very night for his re-embarkation. Under cover of the darkness he huddled his troops on board; and next morning the triumphant Britons beheld the invaders' fleet far on their flight across the Narrow Seas. SECTION E. Caesar worsted--New fleet built--Caesar at Rome--Cicero--Expedition of 54 B.C.--Unopposed Landing--Pro-Roman Britons--Trinobantes --Mandubratius--British army surprised--"Old England's Hole." E. 1.--Caesar too had, on his side, gained what he wanted, though at a risk quite disproportionate to the advantage. So much prestige had he lost that on his disembarkation his force was set upon by the very Gauls whom he had so signally beaten two years before. Their attack was crushed with little difficulty and great slaughter; but that it should have been made at all shows that he was supposed to be returning as a beaten man. However, he now knew enough about Britain and the Britons to estimate what force would be needful for a real invasion, and energetically set to work to prepare it. To make such an invasion, and to succeed in it, had now become absolutely necessary for his whole future. At any cost the events of the year 55 must be "wiped off the slate;" the more so as, out of all the British clans, two only sent in their promised hostages. Caesar's dispatches home, we may be sure, were admirably written, and so represented matters as to gain him a _supplicatio_, or solemn thanksgiving, of twenty days from the Senate. But the unpleasant truth was sure to leak out unless it was overlaid by something better. It did indeed so far leak out that Lucan[89] was able to write: _Territa quaesitis ostendit terga Britannis_.
