stand was made at some unidentified place, conjectured to have been at Key Coll Hill, near Newington. But, thenceforward, the accounts left by Caesar and by early British writers grow confused. Whether the victorious general, in pursuit of Cassivelaunus, crossed the Thames at London, or whether "Coway Stakes," near Weybridge, mark the scene, will never be known. But when he had penetrated into Hertfordshire, and had humbled the British king to the point of asking for peace, Caesar found it was time to return to Gaul. Exacting hostages, he commenced his retreat. Harassed by flying bands of natives, who cut off stragglers and placed obstacles in his line of march, he reached Deal in September, sailing thence on the 26th of that month. Thus ended Caesar's second and last invasion of Britain. He had been six weeks in the island; had marched a hundred miles into its dense forests, and had humbled the native princes. But winter was approaching, and it was dangerous to delay. He returned to the Continent, a victor, with hostages, prisoners, and promises of tribute; but he left many of his expedition, dead, behind him. And it is significant of how hazardous these invasions were, that not until another ninety-six years had passed did another Roman so much as land on these shores. [Illustration: BARHAM DOWNS.] The camp which Caesar constructed along Barham Downs is still to be seen. On this wild and worthless tract of land which has never known cultivation, the marks of the spade will exist for many centuries if left undisturbed by new-comers. And although many historic gatherings have taken place here, no entrenchments have been made since the defeat of the Britons in B.C. 54. King John's army of sixty thousand men encamped here in 1213, to withstand the French invasion, and Simon de Montfort, somewhat later, at the head of disaffected Barons; Henrietta Maria held her first Drawing Room here in a tent, while on her way to be married to Charles the First at Canterbury; and, centuries afterwards, a great army encamped on Barham Downs in readiness for Napoleon's projected invasion. But on none of these occasions were any earthworks thrown up, and the fosses and ditches that still remain to be explored are of undoubted Roman construction. [Sidenote: COLDHARBOURS]
