G. A. Henty,
Under Wellington's Command: A Tale of the Peninsular War
“ Fortunately, none were so seriously disabled as to be unfit to take their places in the ranks. The necessity for absolute silence was impressed upon them, and they were told to march very carefully; as a fall over a stone, and the crash of a musket on the rocks, might at once call the attention of a French sentinel. As the troops filed out through the entrance to the redoubt, Terence congratulated himself upon their all having sandals, for the sound of their tread was faint, indeed, to what it would have been had they been marching in heavy boots. ”
