Captain Kincaid and his troops began to cheer when they heard the British lines advancing far to the right, signaling Lord Wellington's order to pursue the retreating French forces. Emerging from the thick smoke, Kincaid witnessed an exquisite scene of the French army in disarray and retreat, as British and Prussian lines pursued them into the distance. This movement cleared the smoke and revealed the victory over Napoleon, relieving the anxiety of the long and destructive battle.
