Leopoldsrühe's garrison was few and when the Spartican soldiers were on sight they were caught off guard. Leopoldsrühe's centre had a small fort, built in the early 1500s by the Sparticans when it was taken. The 300 guards and the mayor quickly rushed in the redoubt, leaving the citizens behind, unprotected.
Earlier, a soldier on horseback saw the massive Spartican army marching, and immediately rushed to Fort Bergnitz, a military garrison south of Leopoldsrühe. He warned the garrison's commander about them, the commander was shocked. He ordered all of the 4,000 soldiers to mobilise and march to Leopoldsrühe, while the soldier was tasked to bring a letter to the capital and effectively the president, about the surprise Spartican invasion force.
Meanwhile, the soldiers of Bergnitz quickly rushed to Leopoldsrühe at approximately 10 AM.
