Cause → Event → Consequence
Following the Defenestration of Prague on 23 May 1618, Bohemian Protestant nobles established a new government under Jindřich Matyáš Thurn. A Habsburg Catholic army under Count Bucquoy advanced toward Prague but was delayed near Čáslav and later forced to withdraw due to supply shortages and illness, prompting Thurn to pursue the retreating imperial force.
Count Thurn followed Bucquoy's withdrawing army and forced an engagement near the village of Lomnice nad Lužnicí in southern Bohemia. Part of the Catholic force was trapped between two ponds and subjected to heavy artillery fire. The battle ended in a clear Protestant victory, with Bucquoy's army losing at least 1,500 men.
The defeat compelled the main Habsburg army to withdraw from Bohemia entirely. However, the Protestant forces failed to pursue and destroy the retreating Catholics, forfeiting an opportunity to deliver a decisive blow. The Habsburg army survived to fight another day, prolonging the conflict that would escalate into the broader Thirty Years' War.
