A horseman dashed across the narrow bridge. He was riding for his life, which each moment seemed to place in greater jeopardy, for in hot pursuit of him were some thirty Austrians. Mounted on white horses and with their white uniforms, they looked in the dim light like specters. They were gaining rapidly on the flying man, for his horse was almost done, and theirs seemed fresh enough.

The Emperor caught sight of what was going on, and made his way quickly to the picket. Meanwhile, all was bustle with them. The men had sprung to their feet and formed themselves into some sort of order to receive the enemy, whom they much outnumbered.

Meantime, the fugitive kept advancing, urging, by whip and spur, his jaded steed to greater efforts. Safety seemed almost in his grasp, and, encouraged by the presence of his compatriots, he waved his hand aloft, and shouted, "France and the Emperor!"

The picket cheered in response, and, with cries of "Vive l'Empereur," rushed to meet their foe. Then both sides went at it pell mell; shots were fired, but these soon ceased when the combatants got to close quarters; then it became a hand to hand struggle between swords and bayonets, and cuts and thrusts were freely exchanged, to the accompaniment of shouts and cheers from those who were unhurt, and groans from the wounded and the dying. Other Austrians swam their horses across the river to the assistance of their comrades, and, for the moment, despite the stubborn resistance of the French, who yielded only inch by inch, victory inclined to the attacking side. But soon reinforcements poured in on the French side, and the engagement raged more furiously than ever. For a short space the outpost seemed in danger, for Austrian troops on the other side of the river were collecting and hurrying across. But at this juncture, just when affairs were looking critical for Napoleon's men, some guns from the heights in possession of the French opened fire, sweeping the plains across the Danube. The hailstorm of grape and canister was murderous, and, there being no shelter for them, the Austrians first wavered and then incontinently took to flight. The small body on this side of the river were thus isolated, and could make no further stand against the dash and élan of the French. So the retreat was sounded and the survivors of them galloped across the bridge, followed by a storm of musket shots from the victorious enemy, that brought many a white uniform to the dust. Few of them, indeed, regained their comrades. The whole affair had occupied but a few minutes, and Napoleon, who had mounted a trooper's horse, and ridden up to the picket at the outset, had sat watching it immovably throughout.

When all was over, the flying horseman, who had so narrowly escaped capture, gained his side. Then, reining in his panting charger, he saluted.

"Whence come you, Sir," asked the Emperor sternly.

"From France, Sire, with despatches, marked immediate, from the Empress," was the prompt reply.

"Follow me to my tent, if your horse can carry you so far. Then I will see that the Empress's communication receives attention." And, to suit his pace to the new-comer's, he moved on at a walk, the other in his wake.

Arrived at the tent, Napoleon woke his secretary; he wanted him to write his answer to Josephine's despatch.

St. Just, for he was the courier who had so nearly lost his life, had not expected to find another person present, and felt embarrassed. Knowing the subject of the Empress's communication, he wished to have his interview with the Emperor alone. He hesitated for a moment, and then said deprecatingly:—"The Empress strictly charged me, Sire, to give you these papers when you were alone."
