In Caesar's second and longer invasion in the next year (54 B.C.), when his 28 many-oared triremes and 560 transports, &c., in all 800, poured on the same Kentish coast 21,000 legionaries and 2,000 cavalry, there is little doubt that his strong foot left its imprint near that cluster of stockaded huts (more resembling a New Zealand pah than a modern English town) perhaps already called London--Llyn-don, the "town on the lake." After a battle at Challock Wood, Caesar and his men crossed the Thames, as is supposed, at Coway Stakes, an ancient ford a little above Walton and below Weybridge. Cassivellaunus, King of Hertfordshire and Middlesex, had just slain in war Immanuent, King of Essex, and had driven out his son Mandubert. The Trinobantes, Mandubert's subjects, joined the Roman spearmen against the 4,000 scythed chariots of Cassivellaunus and the Catyeuchlani. Straight as the flight of an arrow was Caesar's march upon the capital of Cassivellaunus, a city the barbaric name of which he either forgot or disregarded, but which he merely says was "protected by woods and marshes." This place north of the Thames has usually been thought to be Verulamium (St. Alban's); but it was far more likely London, as the Cassi, whose capital Verulamium was, were among the traitorous tribes who joined Caesar against their oppressor Cassivellaunus. Moreover, Caesar's brief description of the spot perfectly applies to Roman London, for ages protected on the north by a vast forest, full of deer and wild boars, and which, even as late as the reign of Henry II., covered a great region, and has now shrunk into the not very wild districts of St. John's Wood and Caen Wood. On the north the town found a natural moat in the broad fens of Moorfields, Finsbury, and Houndsditch, while on the south ran the Fleet and the Old Bourne. Indeed, according to that credulous old enthusiast Stukeley, Caesar, marching from Staines to London, encamped on the site of Old St. Pancras Church, round which edifice Stukeley found evident traces of a great Praetorian camp. However, whether Cassivellaunus, the King of Middlesex and Hertfordshire, had his capital at London or St. Alban's, this much at least is certain, that the legionaries carried their eagles swiftly over his stockades of earth and fallen trees, drove off the blue-stained warriors, and swept off the half-wild cattle stored up by the Britons. Shortly after, Caesar returned to Gaul, having heard while in Britain of the death of his favourite daughter Julia, the wife of Pompey, his great rival. His camp at Richborough or Sandwich was far distant, the dreaded equinoctial gales were at hand, and Gaul, he knew, might at any moment of his absence start into a flame. His inglorious campaign had lasted just four months and a half--his first had been far shorter. As Caesar himself wrote to Cicero, our rude island was defended by stupendous rocks, there was not a scrap of the gold that had been
