In my surprise I had dug spur and pushed out beyond our clump of firs, almost before it struck me that the sound came not from the valley but from ahead of us, across the road and some way up the slope. My first motion had been to charge the troopers in the roadway, to drive them (or at least to check them) from helping at the bridge; and I had done more wisely by holding to it, even upon second thought, for they had wheeled towards the sound and so gave their backs to us. While they stood thus we might have charged through them, and all had been well. As it was, they offered us this chance for a moment only; and then, striking spur, scrambled up the bank on the far side of the road and headed across the turf at a gallop. We looked, and slowly we understood. For half a mile away, up the rise of the downs, a broad dark shadow was moving; and we had scarcely discerned it before, in the pale of the dawn, small points of light wavered and broke upon morions, gorgets, cuirasses. That moving shadow was our own main body, climbing the hill at a gentle trot. A few picketers hung on their rear. It was these, of course, that had given the alarm: and by-and-by the trumpets taking it up on Five Barrow Hill, a body of four hundred horse came over the rise at a gallop and bore down obliquely on the mass--very confidently at first: but at closer quarters it lost heart and started off to harass the right flank of the solid mass, that paid it little attention and held on its way without swerving. Before this we had put our horses in motion, to overtake the patrol (as I will call it) and break through to join our comrades. But here it was that our delay proved fatal. For turning at the sound of our gallop, and belike judging us to be the advance-guard of a second large body of horse, the leader of the patrol wheeled his men about, halted them for a moment, and so charged them straight down upon us. In numbers they were more than two to one, with the advantage of the slope, and albeit we fought fiercely for a minute, they broke us and drove us back headlong on the road. Nor did they stop here, but, having us on the run, headed us right down the road to the bridge. Here, at the bridge-head, finding it unguarded, I managed to wheel about and beat off a couple of pursuers: and Israel Hutson and one of the troopers joining me, we three blocked the passage and could not be dislodged. For the bridge was extremely narrow; so narrow, indeed, that in either parapet the builders had provided an embrasure here and there, for the foot-traveller to step aside if he should meet a passing wagon.
