Pariset explained, when Kenneth questioned him, the importance to the enemy of the capture of Liége. Encircled by its twelve forts, constructed by the engineering genius of General Brialmont, the town stood as a formidable obstacle to the advance of the Germans through the valley of the Meuse, the easiest way into France. Every day it could be held was a day's delay in the prosecution of the enemy's plan of campaign, which, as everybody knew, was to crush France before Russia had time to threaten Germany on her eastern border.

"The Germans have, they think, a very perfect military machine," Pariset continued; "I daresay they have, though perhaps they are a little too cocksure about it. They've had no experience of war for forty years, and their easy victory in 1870 has possibly produced what you call swelled head. Anyhow, the most perfect machine may be dislocated by a little grit, and Liége, we hope, will be the little grit for the occasion. Now we had better get some lunch; then we'll fly north. I'll report myself to my commandant, and ask for leave to carry you to Ostend."

They walked away to the rear of the lines, towards a cottage on which the canteen flag was flying. Before they reached it they met a general officer on horseback, cantering along accompanied by an aide-de-camp. Pariset saluted, the officers touched their hats and passed.

"General Leman, commanding the forts," said Pariset.

"He looked just like an Englishman," Kenneth replied.

Pariset smiled, and was beginning a chaffing remark when he was hailed from behind. Turning, he saw that the officers had reined up, and turned their horses' flanks towards him. He hurried back, Kenneth taking a step or two in the same direction.

"Lieutenant Pariset, I understand?" he heard the general say. "I compliment you on your little exploit. You did very well; thank you!"

Pariset murmured something, saluted again, and the officers rode off.

"He didn't give me time to tell him about you," said Pariset, rejoining his friend. "He is evidently in a hurry to get back to Fort Loncin."

"It doesn't matter about me," said Kenneth. "How did he know about it at all?"
