Across the great tunnel to the north of Bellicourt, where the Canal passes for nearly two miles underground, ran the main Hindenburg system, carrying it eastwards over the Canal itself, and it was here that the fiercest resistance was put up.

The two American divisions had the post of honour and led the advance.

It was a heavy task, largely owing to the fact that it had not been possible to master the German outpost line completely before the advance started, and numerous small bodies of the enemy, left behind in machine-gun posts, tunnels, and dug-outs, were able to harass it seriously for a time.

But the "Americans fought like lions"-- how often I heard that phrase from our own men in France! The American losses were no doubt higher than would have been the case with more experienced troops, seasoned by long fighting,--so I have understood from officers present at the battle.

It was perhaps partly because of "their eagerness to push on" without sufficiently clearing up the ground behind them that they lost so heavily, and that advanced elements of the two divisions were for a time cut off.
