‘Then a good day to you!’ Arthur spurred his horse and galloped on for a final inspection of his other brigades before returning to his command post. By the time he returned to the crest of the small hill south of Vimeiro, the enemy had swung round to the west and was forming columns in readiness to launch their assault. Arthur glanced north and was satisfied that the army was ready to repel any attacks they might face.The two brigades on the right flank were concealed behind the crest of Vimeiro Hill, on which twelve cannon had been positioned to cover the slopes. Down below, in the cover of boulders and folds in the ground, crouched the light infantry and two companies of rifles. Arthur nodded to himself with satisfaction. Now he would put his ideas to the test and see just how formidable the French assault columns really were.

A dull boom echoed up the slope and he saw a puff of smoke some half a mile from the foot of the ridge. Abruptly several more guns opened fire and kicked up small explosions of dirt, rock and small branches as the grapeshot tore up the ground along his skirmish line. After a few more rounds the French guns fell silent and a moment later the enemy skirmishers advanced to duel with their British counterparts. A steady crackle of musket and rifle fire drifted up the slope as the skirmishers of both sides contested the foot of the hill. Then, as weight of numbers began to tell, the British fell back, scurrying from cover to cover as they fired on their pursuers. A deep drum roll and tinny blare of trumpets carried across from the French lines as the assault columns edged forward and began to tramp up the slope behind their skirmishers.

‘And here they come,’ Somerset muttered casually.

There was a low fold in the ground just in front of the British cannon and the riflemen took shelter there as the other skirmishers ran back to their battalions and joined the main battle line. Then, as the first of the French skirmishers came into plain view, closely followed by the heads of the assault columns, the British guns opened fire. Arthur watched with keen interest the effects of the three howitzers he had deployed alongside the other guns. They were firing the newly developed shells designed by an artillery officer named Shrapnel, which were fused to burst over the heads of the enemy, spraying out scores of small iron shards. As Arthur watched, the first of the shells burst in a white puff over the leading ranks of the nearest column and at once a score of men went down.
