“There!” he exclaimed. “That would make a magnificent battlefield.”

I knew his enthusiastic fondness for the study of military history and the details of battles. In common with most other people who have seen nothing of war, I had never been able to picture a battle in my mind; and in reading history I had always found it difficult to comprehend the topographical descriptions of battlefields, or to understand the influence of hill and dale, of copse and stream, upon the issue of a combat. Bernard had mastered the whole subject. He had often moulded in soft earth for my instruction miniature, but exact, representations of many famous battlefields.

The ground we were on was a chain of hills crossing a public thoroughfare, and my friend soon grew enthusiastic in his account of how one army would be posted here, and the other there; how the flanks of each would rest upon certain protected points and how the attacking force would try to carry this or that position.

“If the attacking general knows his business,” he said, “he will strain every nerve to drive his adversary from that little knoll there. And if he succeeds in planting a battery or two there, properly supported, his enemy will have to charge him out of the place or reconstruct his own lines, and to reconstruct them will cost him half the value of his position.”

A new look came into Bernard’s face. The smile had gone from his lips, the great sad look was in his eyes. Gazing at me with intense earnestness, he cried out: “He must drive them back. If they once hold that knoll—”

Bernard paused, grew very pale, and then said with some difficulty with his vocal organs: “Let’s gallop away from here.”

I followed his retreating form, and when we drew rein again, we were a full mile distant from the place of this field lecture. My friend had meantime regained his color and composure, but the old smile had not yet returned to his lips.

“Are you ill, Bernard?” I asked.

“No, I am quite well, thank you.”

“Then what—”
