One by one the enemy’s strongholds fell to the British forces, and the stores of arms and food that could not be carried off were set on fire. As the summer heat beat down on the parched landscape the campaign assumed a steady rhythm of marching during the cool hours before dawn and into the morning, before lying up during the suffocating midday heat, and then resuming their progress into the early evening before making camp for the night. The only relief from marching came when they encountered each stronghold, which fell in less than a day, and then the column moved on.

As July began with still no sighting of Dhoondiah Waugh and his army Arthur began to doubt that his campaign plan was working. The British were steadily whittling down the enemy’s supply bases and reducing his strongholds and yet Dhoondiah Waugh resolutely refused to give battle, even though he surely knew where Arthur’s column was from day to day, since his horsemen were nearly always in sight somewhere in the hazy distance, keeping a watch on the column’s progress.

‘The bloody man is going to retreat to the ends of the earth,’ Fitzroy grumbled one morning early in the month. He was riding at Arthur’s side, and squinting in the harsh glare of the sun. The dust kicked up from the column filled the air and settled on the jackets and crossbelts of the battalion marching beside them so that it seemed as if they had all passed through a pool of ochre dye.

Arthur licked his lips and spat out the grit that had got caught in his saliva. ‘He can’t go too far. If Goklah is true to his word then even now he will be moving towards us with his army. Dhoondiah Waugh will have a battle on his hands whichever way he turns. There will be no escape.’

‘I pray so,’ Fitzroy muttered. ‘Before we all choke on this wretched dust. I imagine you’ll be looking forward to returning to the comforts of Seringapatam as much as the rest of us, sir?’

‘Yes. I suppose so,’ Arthur replied. His mind went back to one of the final communications he had received from Richard, shortly before setting off on the present campaign. Another attempt was to be made to take Java, to secure the trade routes from French privateers. Richard had asked him to consider taking command of the expedition once he had dealt with Dhoondiah Waugh. Although the idea attracted him, Arthur had been forced to set it aside while the present campaign was under way. His thoughts were interrupted by the sudden pounding of hooves as a rider came galloping down the column.

‘Wellesley, sahib?’ the man called out. ‘Colonel Wellesley?’

‘Here!’ Arthur raised his hat and waved it from side to side as he halted Diomed.
