Alfred I, Prince of Windisch-Grätz

General Alfred Candidus Ferdinand, Prince of Windisch-Grätz (German: Alfred Candidus Ferdinand Fürst zu Windisch-Grätz; 11 May 1787 – 21 March 1862), a member of the Bohemian noble Windisch-Graetz family, was a Field Marshal in the Austrian army. He is most noted for his service during the Napoleonic Wars and for his role in suppressing the Revolutions of 1848 in the Austrian Empire.

Originally from Styria, the Windisch-Graetz dynasty had received Inkolat rights of nobility by the Bohemian Crown in 1574. Alfred was born in Brussels, then capital of the Austrian Netherlands, the son of Count Joseph Nicholas of Windisch-Graetz (1744–1802) and his second wife, Duchess Maria Leopoldine Franziska of Arenberg. The family took its residence at Tachau (Tachov), the lordship had been purchased by Alfred's father in 1781.

On 15 June 1817 he married Princess Eleonore of Schwarzenberg.

He started service in the Habsburg imperial army in 1804. As an Austrian army officer he distinguished himself throughout the wars fought by the Habsburg Monarchy in the 19th century.

Windisch-Grätz participated in all the wars against Napoleon and fought with distinction at the Battle of Leipzig and in the campaign of 1814. In 1833, he was named Lieutenant Field Marshal (made Field Marshal (German: Feldmarschall) in October 1848).

In the years of peace that followed, Windisch-Grätz held commands in Prague, being appointed head of the army in Bohemia in 1840. Having gained a reputation as a champion of energetic measures against revolution, during the Revolutions of 1848 in Habsburg areas he was called upon to suppress the March 1848 insurrection in Vienna. However, finding himself ill-supported by government ministers he resigned from his post.

After returning to Prague, his wife was killed by a stray bullet during the popular uprising.He then showed firmness in quelling an armed outbreak of the Czech separatists (June 1848), declaring martial law throughout Bohemia. Upon the recrudescence of revolt in Vienna he was summoned to head a large army that reduced the city through a formal siege by October 1848.

Appointed to the chief command against the Hungarian revolutionaries under Lajos Kossuth, he gained some early successes and reoccupied Buda and Pest (January 1849), but by his slowness in pursuit he allowed the enemy to rally in superior numbers and to prevent an effective concentration of the Austrian forces.

In April 1849 he was relieved of his command and thereafter rarely appeared again in public life.
