After our defeat at Horsham, the Russians had contented themselves by merely driving back the defenders to a line of resistance from Aldershot to the north of Bagshot, and then they had marched onward to Birmingham. From Horsham, however, two columns of the invaders, mostly French, and numbering over twenty thousand each, had advanced on Guildford and Dorking. At the same time, a strong demonstration was made by the enemy in the country north of Eastbourne and Hailsham, by which the whole of the district in the triangle from Bexhill to Heathfield, and thence to Cuckfield and Steyning, fell into their hands. The British, however, had massed a strong force to prevent the enemy making their way into West Kent, and still held their own along the hills stretching from Crowborough to Ticehurst, and from Etchingham, through Brightling and Ashburnham, down to Battle and Hastings. The north of London had during the weeks of hostilities been strongly guarded by Volunteers and Regulars, for information of a contemplated landing in Essex had been received; and although the defenders had not yet fired a shot, they were eagerly looking forward to a chance of proving their worth, as their comrades in other parts of England had already done. At first the tactics of the invaders could not be understood, for it had been concluded that they would naturally follow up their successes on landing with a rapid advance on London. It was, of course, evident that the vigorous demonstrations made in the North and other parts of Britain were intended with a view to drawing as many troops as possible from the defence of London, and dispose of them in detail before surrounding the capital. Yet, to the dismay of the enemy, no blow they delivered in other parts of our country had had the desired effect of weakening the defensive lines around London. At the opening of the campaign it had been the enemy's intention to reduce London by a blockade, which could perhaps have been successfully carried out had they landed a strong force in Essex. The troops who were intended to land there were, however, sent to Scotland instead, and the fact that they had been annihilated outside Glasgow resulted in a decision to march at once upon the metropolis. Advancing from Horsham, the French right column, numbering 20,000 men with about 70 guns, had, after desperate fighting, at last reached Leatherhead, having left a battalion in support at Dorking. The British had resolutely contested every step the French had advanced, and the slaughter around Dorking had been awful, while the fighting across Fetcham Downs and around Ockley and Bear Green had resulted in frightful loss on both sides.
