The Battle of Teutoburg Forest occurred in 9 CE, during the reign of Roman Emperor Augustus.

Arminius, a Cheruscan chieftain, was instrumental in uniting Germanic tribes against the Roman forces.

Publius Quinctilius Varus, a Roman governor, underestimated the strength of the Germanic alliance and fell into their trap.

Three Roman legions, Legions XVII, XVIII, and XIX, were ambushed and destroyed by the Germanic forces.

The defeat at Teutoburg Forest halted Roman expansion into Germania and forced them to abandon their plans for conquering the region.

Tiberius, the successor of Augustus, led several campaigns against the Germanic tribes in an attempt to avenge the defeat at Teutoburg Forest.

Germanicus, the adopted son of Tiberius, defeated Arminius in the Battle of Idistaviso, but failed to capture or kill him.

Thusnelda was captured by the Romans and provided valuable information about Arminius's plans, which helped the Romans achieve victory at Idistaviso.

Arminius was assassinated by his fellow Germanic tribesmen, who were jealous of his power and influence.

Tacitus, a Roman historian, provided a detailed account of the Battle of Teutoburg Forest in his historical work 'Annals'.

The Romans constructed a fort called Aliso near the site of the battle to commemorate their victory and maintain a military presence in the region.

The Battle of Teutoburg Forest demonstrated the effectiveness of ambushes and surprise attacks in defeating a superior force, which had a lasting impact on military tactics and strategies.

The Battle of Teutoburg Forest occurred in the region that is now part of modern-day Germany.

Detmold is the modern-day town closest to the site of the Battle of Teutoburg Forest.
