A blow from one of the gendarmes laid him flat on the ground. At the same instant three men jumped on Sam Hickey. They took him so utterly unawares that he had not made the slightest resistance.

"Get away, you fools! Don't you know——"

Hickey's breath was fairly knocked out of him. He was at the bottom of the pile, unconscious almost the next second.

The Battleship Boys had gone down fighting valiantly, the lads whom the readers of this series now know so well. They were the same boys who, in "The Battleship Boys at Sea," enlisted in the United States Navy, serving their apprenticeship at the Training Station in Newport. It was there that they proved by their faithful attention to duty, their courage and fitness to serve the Flag of their country. Then, on board the battleship "Long Island," it will be recalled how Dan Davis whipped the bully of the ship in a fair stand-up battle; how Hickey was punished for an offence for which he was not wholly to blame, being confined to the brig on rations of bread and water; and how finally both lads proved themselves by their heroic rescue of a drowning diver. The latter was the man who had been responsible for all their trouble on shipboard. For their bravery in facing almost certain death the boys were rewarded by a grateful government in the bestowal of that much-coveted decoration, the medal of honor.

Again, in "The Battleship Boys' First Step Upward," the reader will remember Sam Hickey's having sighted a "shooting star," while on lookout duty, and that the shooting star was a rocket signal of distress from a sinking schooner. It will be recalled how Dan Davis was left alone on the doomed ship; how the battleship turned its big guns on the schooner, shooting the decks from beneath his feet, and how, in the end, the plucky lad saved the schooner and its cargo. Dan's heroic effort in saving a boat load of men from almost certain destruction by a rushing torpedo, and his winning of a promotion to the grade of petty officer will also still be fresh in the reader's mind.

And now the boys were on their first foreign cruise. The battleship "Long Island" had come to anchor off Boulogne, France. The Battleship Boys had asked for a shore leave of one week, which was readily granted to them. In that time they had planned to visit Paris and London, which they would have ample time to do, and rejoin their ship before their leave of absence expired.

They had arrived in Paris that morning, after an all-night ride on one of the fastest express trains in France, but which Sam Hickey had referred to under the undignified title of "milk train."

After considerable difficulty they had secured lodgings at a pension, as the boarding houses in France are called, and had at once started out to see the city. This they did with the aid of a map. They were self-reliant boys, and the thought of getting lost did not trouble them at all.

During the afternoon they had wandered off along the fashionable avenue, the Bois de Boulogne, and into the beautiful park of the same name, where they lingered until nearly night. Hunger alone brought them to a realization that it was time they sought their lodgings. So anxious were they to see Paris, that they had forgotten all about breakfast, and, when noon arrived, they saw no place where they could procure food.

They were on their way back when they met with the adventure that now promised to involve them in serious difficulty. They had assaulted a body of men who were police officers of the republic of France.
