That was not entirely true, he reflected. That mob would do more than hurt Arthur and his men if they found a way into the arsenal. But it was a solid enough building and would keep the Nizam’s men at bay for a while yet. Long enough for the other columns to arrive.

Then he saw some of the men at the rear of the crowd take up a solid-looking water trough. They emptied the water out of it, then lifted it up and bore it through the crowd towards the arsenal. A makeshift battering ram, he realised with a sick feeling. He must not let them have a chance to use it against the doors.

‘Stand up!’ Arthur shouted to his men. ‘Present!’

The muskets swung up and levelled as the sepoys took aim on the mob. At once there were cries of terror and men flinched and fell back. Arthur leaned over the ramparts and stretched his arms open.

‘Hear me! Hear me, I say!’

It took a while for the frightened protesters to grow silent, and still scores of them were slipping back into the heart of the crowd.

‘I am Colonel Wellesley. I am here on the authority of the Nizam. He has given orders for the disbandment of the French-officered battalions.You will lay down your weapons and return to barracks now!’

This provoked a fresh outburst of rage from the crowd and the makeshift battering ram surged forward again. Arthur turned to the section of men covering the rampart over the entrance. ‘Take aim on those men carrying the water trough!’

The muskets went up to their cheeks as the men squinted down the barrels towards the approaching crowd.

‘Cock your weapons, but do not fire unless I give the order!’

The sepoys thumbed back the cocks, ready to fire a volley of heavy lead balls into the crowd in front of the arsenal. The ram came on, and there was a jarring thud as it struck home against the wall.

‘Shoot over their heads!’ Arthur called to the nearest men and they raised their barrels.‘Fire!’The volley roared out with a series of stabs of fire and a small rolling bank of gunpowder smoke.The crowd paused for only an instant before they realised the shots had been fired wide deliberately. Then they came forward again and there was another thud from below. Arthur swallowed. The time had almost come when he would have to open fire on the crowd in order to survive.

‘Reload, and prepare volley fire!’
