During the Battle of Roliça (Napoleon was defeated, as his officers failed to carry out his orders), The French captured a British Colonel and took him to Napoleon, who questioned him without success. Just as the Colonel was led away, Napoleon asked him why the British officers wore those scarlet coats. The Colonel proudly answered: " Because if we are hit, the blood will not show, and the troops will not panic!" Napoleon considered the answer, and called for pen and paper. He scribbled an order - - and, from then on, his officers wore brown pants.
