I wondered, and I supposed the others did, why we had fought each other at all. I looked at the Highlander, who was falling to sleep, exhausted, and in spite of his drawn face and mud-stained uniform, he looked the embodiment of freedom. Then I thought of the Tricolor of France and all that France had done for liberty. Then I watched the German, who had ceased to speak. He had taken a Prayer Book from his knapsack and was trying to read a service for soldiers wounded in battle. And ... while I watched him, I realized what we were fighting for.... He was dying in vain, while the Britisher and myself, by our deaths, would probably contribute something toward the cause of civilization and peace.
