The Battle of Zasek which occured in 849 is a major loss of Louis the German against the Bohemians. He was defeated at the border between the 2 realms.

Context
Charlemagne's son Charles conquered Bohemia during the years 805-808 with notably the battle of Canburg in 805 where Lech prince of the Bohemians died. After that, Bohemians were under Frankish Suzerenty. They were mentioned in "Ordinatio imperii" in 817 and appeared in Annales regni francorum at the diet of Frankfurt in 822. Between 822 and 840, the Bohemians were emancipated from the Franks which led to the Franks trying to conquer them back into the empire. The Bohemians tried to de-escalate the situation with 14 princes converting to Christianity the 13 January 845. But in 846, Louis the German defeated Mojmir I, a Christian prince of Moravia thus making them return to their ancient beliefs. They made a campaign in 847 with little success since the Bohemians gave them hostages. In August 848, the Bohemians attacked back into the empire but they were defeated and forced to negotiate.

The Battle
The battle is documented in "Annales Fuldenses". In the year 849, Duke Thachulf and Duke Ernst led a great campaign against the Bohemians. Louis couldn't assist since he was ill. They thought the Czech weren't ready but they were. They organized and sabotaged the road and felled trees pointing to the enemy. They resisted the Franks's invasion forcing Thachulf to start negotiations. The Bohemians accepted but the Franks attacked them during the negotiations. The Bohemians managed to kill and imprison the Franks and those who weren't were surrounded by the Bohemian army. Now the Franks had to beg the Bohemians for peace and the peace treaty was harsh.

Consequences
This Victory made Bohemians completely independent of the Franks. They tried in 855 to invade Bohemia but the result is not known. In 857, They invaded the realm of the son of Wistrach, Slavitah and he went to Moravia. No major invasion of bohemia happend until 872 and the battle of Vltava.
