Arthur took one last look at the unequal fight engulfing the Twenty-Ninth and then urged his mount forward, riding to join the rest of the army as it began to advance towards the waiting Frenchmen. With the skirmishers of the Rifles and the Light Companies of the other battalions leading the way, the British troops began to move up over the boulder-strewn slopes and gullies. As the skirmishers from both sides met there was a steady crackle of musket fire and shouted orders, and cries of pain and the wild exchange of insults and battle cries that echoed off the sides of the valley. Arthur joined the men of the central column as they struggled to advance with dressed ranks. The slopes were too uneven to permit the neat formations that the men had practised on drill grounds back in Britain. Slowly - too slowly, to Arthur’s mind - they made their way up to the crest, while all the time the sound of firing from the direction of the Twenty-Ninth steadily diminished. Ahead of the British line the skirmishers continued to fight it out, but as the first ranks of the leading battalions emerged on to the crest the guns of Delaborde’s single battery opened fire. Cones of lead balls tore through the ranks, opening gaps that were quickly closed by fresh men as the redcoats advanced on the main French position.

Now they were picking their way over the bodies of dead and wounded, British and French alike. A short distance ahead the British skirmishers had halted and gone to ground as they came up against the main French line. The British battalions halted to load their weapons and then continued forward until they were within effective musket range of the enemy, no more than fifty paces away. Then, as the French loosed their first volley and dozens of redcoats went down, the rest calmly halted, raised their muskets, thumbed back the firing hammers and waited for the order.

‘Fire!’

Hundreds of muskets spat flame and smoke in a thunderous roar and then the sergeants bellowed the order to reload.The French fired again and Arthur heard balls zip through the air close by as he strained to gauge the progress of the fight through the eddying smoke. With a pounding of hooves Somerset came riding up, and reined his horse in sharply.

‘How go things with the Twenty-Ninth?’ asked Arthur.

‘They’ve had it, sir. I wasn’t in time to save them.’

‘Had it? What, all of them?’

‘Lake’s dead. So are over two hundred and fifty of his men. The rest are wounded or routed.’

Arthur stared at his aide and muttered, ‘Good God.’
