Hey there everyone! I thought it would be nice to share some important battles in history. This thread will probably be updated once every week depends on how busy I am. But first off we will start with Vienna, Austria-Ottoman Wars, 1529


The Ottoman Turks' unsuccessful siege of Vienna in 1529 marked the beginning of the long decline of their empire. It also stopped the advance of Islam into central and western Europe, and ensured that the Christian rather than the Muslim religion and culture would dominate the region.

In 1520, Suleiman II had become the tenth sultan of the Ottoman Empire, which reached from the Persian frontier to West Africa and included much of the Balkans. Suleiman had inherited the largest, best-trained army in the world, containing superior elements of infantry, cavalry, engineering, and artillery. At the heart of his army were elite legions of Janissaries, mercenary slaves taken captive as children from Christians and raised as Muslim soldiers. From his capital of Constantinople, the Turkish sultan immediately began making plans to expand his empire even farther.

Suleiman had also inherited a strong navy, which he used with his army to besiege the island fortress of Rhodes, his first conquest. Granting safe passage to the defenders in exchange for their surrender, the Sultan took control of Rhodes and much of the Mediterranean in 1522. This victory demonstrated that Suleiman would honor peace agreements. In following battles where enemies did not surrender peacefully, however, he displayed his displeasure by razing cities, massacring the adult males, and selling the women and children into slavery.

By 1528, Suleiman had neutralized Hungary and placed his own puppet on their throne. All that now stood between the Turks and Western Europe was Austria and its Spanish and French allies. Taking advantage of discord between his enemies, Suleiman made a secret alliance with King Francis I of France. Pope Clement VII in Rome, while not allying directly with the Muslim Sultan, withdrew religious and political support from the Austrians.

As a result, by the spring of 1529, King Charles and his Austrians stood alone to repel the Ottoman invaders. On April 10, Suleiman and his army of more than 120,000, accompanied by as many as 200,000 support personnel and camp followers, departed Constantinople for the Austrian capital of Vienna. Along the way, the huge army captured towns and raided the countryside for supplies and slaves.

All the while, Vienna, under the able military leadership of Count Niklas von Salm-Reifferscheidt and Wilhelm von Rogendorf, prepared for the pending battle. Their task appeared impossible. The city's walls, only five to six feet thick, were designed to repel medieval attackers rather than the advanced cast-cannon artillery of the Turks. The entire Austrian garrison numbered only about 20,000 soldiers supported by 72 cannons. The only reinforcements who arrived in the city were a detachment of 700 musket-armed infantrymen from Spain.

Despite its disadvantages, Vienna had several natural factors supporting its defense. The Danube blocked any approach from the north, and the smaller Wiener Back waterway ran along its eastern side, leaving only the south and west to be defended. The Vienna generals took full advantage of the weeks before the arrival of the Turks. They razed dwellings and other buildings outside the south and west walls to open fields of fire for their cannons and muskets. They dug trenches and placed other obstacles on avenues of approach. They brought in supplies for a long siege within the walls and evacuated many of the city's women and children, not only to reduce the need for food and supplies but also to prevent the consequences if the Turks were victorious.

One other factor greatly aided Vienna: the summer of 1529 was one of the wettest in history. The constant rains delayed the Ottoman advance and made conditions difficult for the marching army. By the time they finally reached Vienna in September, winter was approaching, and the defenders were as prepared as possible.

Upon his arrival, Suleiman asked for the city's surrender. When the Austrians refused, he began an artillery barrage against the walls with his 300 cannons and ordered his miners to dig under the walls and lay explosives to breach the defenses. The Austrians came out from behind their walls to attack the engineers and artillerymen and dig counter-trenches. Several times over the next three weeks, the invaders' artillery and mines achieved small breaches in the wall, but the Viennese soldiers quickly filled the gaps and repelled any entry into the city.

By October 12, the cold winds of winter were sweeping the city. Suleiman ordered another attack with his Janissaries in the lead. Two underground mines near the city's southern gate opened the way briefly for the mercenaries, but the staunch Viennese defenders filled the opening and killed more than 1200. Two days later, Suleiman ordered one last attack, but the Viennese held firm once again.

For the first time, Suleiman had failed. Scores of his never-before-defeated Janissaries lay dead outside the walls. The Turkish army had no choice but to burn their huge camp and withdraw back toward Constantinople, but before they departed they massacred the thousands of captives they had taken on the way to Vienna. Along their long route home, many more Turks died at the hands of raiding parties that struck their flanks.

The loss at Vienna did not greatly decrease the power of the Ottoman Empire. It did, however, stop the Muslim advance into Europe. Suleiman and his army experienced many successes after Vienna, but these victories were in the east against the Persians rather than in the west against the Europeans. The Ottoman Empire survived for centuries, but its high-water mark lay somewhere along the Vienna city wall.

Following the battle for Vienna, the countries of the west no longer viewed the Turks and the Janissaries as invincible. Now that the Austrians had kept the great menace from the east and assured the continuation of the region's culture and Christianity, the European countries could return to fighting among themselves along Catholic and Protestant lines.

If Vienna had fallen to Suleiman, his army would have continued their offensive the following spring into the German provinces. There is a strong possibility that Suleiman's Empire might have eventually reached all the way to the North Sea, the alliance with France notwithstanding. Instead, after Vienna, the Ottomans did not venture again into Europe; the Empire's power and influence began its slow but steady decline.
