A peculiar detail from the Battle of Waterloo:

As the day wore on, the French cavalry became more and more desperate, and charged repeatedly with fierce gesticulations, which became more pronounced as they were so continuously repelled. These peculiar looks and gestures of the French became so marked that when the colonel, Fielding Browne, gave the familiar order, ‘Prepare for cavalry,’ the officers would thunder out the order, and add, ‘Now, men, make faces!’
