One of these marches up the Danube is worthy of more minute record. It was leafy June: luxuriant foliage and gorgeous flowers decorated the banks of the river with loveliness which attracted the admiration even of semi-barbarian eyes. The turbulent host, counting within its ranks two hundred and fifty thousand veteran warriors, for many days sauntered joyously along, encountering no foe. War seemed but the pastime of a festival-day. Banners floated gayly in the breeze; music enlivened the march. Arabian chargers pranced proudly beneath their riders, glittering in Oriental gorgeousness of costume. A fleet of gayly-decorated barges filled the stream, impelled by sails when the wind favored, and urged by rowers when the winds were adverse.

Each night, upon some smooth expanse of the river’s banks, the white tents of the invaders were spread, and a city of nearly two hundred thousand inhabitants rose as by magic, with its grassy streets and squares, its busy population, its trumpet-peals from martial bands, and its bannered magnificence blazing in all the regalia of war. Like a fairy vision the city rose in the rays of the declining sun; and like a vision it disappeared in the early dawn of the morning, and the mighty host moved on.

But the black day came. The Turks had ascended the river about a hundred and fifty miles, when they came to a small island called Zigeth. It was strongly fortified, and commanded both banks of the stream. Not another mile could the Moslems advance till this fortress was battered down. Zrini, the heroic Christian commander, and his whole garrison of six thousand men, took an oath that they would surrender the post only with their lives.

Day and night, week after week, the assault continued unintermitted. The besieged, with guns in battery to sweep all approaches, mowed down their assailants with awful carnage; but bastion after bastion was crumbled by the tremendous cannonade of the Moslems: the walls of solid masonry were battered down till they presented but a shapeless pile of rocks. The Turks, reckless of life, like swarming bees swept over the smouldering ruins. They had apparently cut down every inmate of the fort; and, with shouts of victory, were raising the crescent over the blackened and blood-stained rocks, when there was an earthquake roar, and an explosion almost as appalling as the thunders of the archangel’s trump.

Zrini had fired the subterranean vaults containing thousands of kegs of powder. The whole citadel—men, horses, rocks, and artillery—was thrown into the air, and fell a commingled mass of ruin, fire, and blood. The Turks, having lost their leader and a large part of their army, retreated, exhausted and bleeding, but only to gather strength to renew the strife.

Thus year after year these Moslem assaults were continued. Such were the measures the Turks used to convert Europe to Mohammedanism; such were the persuasions urged by the missionaries of the Koran. Shortly after this, the banners of the advance-guard of the Turkish army were seen even from the steeples of Vienna: the majestic host invested the city on all sides.

The renowned John Zobieski, King of Poland, came to the rescue with sixty thousand men. Uniting with the German troops, the combined army fell upon the invaders with almost frenzied courage, utterly routed them, and drove them in wild disorder back to Belgrade. Still, through years of blood and woe, these Moslem assaults were continued. The conquering armies of the Prophet took all of Asia, Egypt, Africa, and Greece. They crossed the Straits of Gibraltar from Africa into Spain, overran the whole Spanish Peninsula, and hung like a black cloud upon the northern cliffs of the Pyrenees, threatening the provinces of France. They swept both banks of the Danube to the walls of Vienna. The Austrian royal family fled at midnight. Itseemed inevitable that all Europe was to be overrun by the Moslems, and that all Christendom was to be cut down beneath their bloody cimeters.

This conflict of Mohammedanism against Christianity continued for five centuries. At one time, the Austrian ambassador at Constantinople wrote to the Emperor Ferdinand in Vienna,—

“When I compare the power of the Turks with our own, the consideration fills me with dismay. I see not how we can resist the destruction which awaits us. They possess great wealth, strength unbroken, a perfect knowledge of the arts of war, patience, union, order, frugality, and a constant state of preparation.

“On our side are exhausted finances and universal luxury. Our national spirit is broken by mutinous soldiers, mercenary officers, licentiousness, intemperance, and a total contempt of military discipline. Is it possible to doubt how such an unequal conflict must terminate? The all-conquering Mussulmans will soon rush with undivided strength, and overwhelm all Europe as well as Germany.”
