Harper and Sharpe are standing next to each other on the rafters in the barn during the first big battle. Sharpe is surprised by a dead soldier and swears. Harper then comes into the barn and warns him of the gate.
Hagman is shot in the head, and he falls on his front with his head facing the left. When Harris crawls over to grab his hand one last time, his head is now turned to the right.
There had been heavy rain in the day and night before the Battle of Waterloo and the ground was very muddy. This actually protected many of the British as French shells landed in deep mud which absorbed much of the blast. The episode depicts the ground as dry and dusty.
When the French are climbing up the ladders, one British soldier falls over without being shot.
When marking the map indicating the route of Napoleon's soldiers, Sharpe uses a modern-looking, "golf"-sized pencil.
