Brennius traveled south and besieged Rome for three days until his brother came to his aid in the invasion. The Romans defended the city for many days and were successful in repelling the invaders. Finally, the two consuls put on armour and joined the men defending the city. They pushed the invaders back but Belinus was able to reform the lines and stop the attacks. Brennius and Belinus continued forward until the walls were breached and the Britons and Gauls invaded the city.
