Veii.
This city was besieged B.C. 400 by the Romans, the siege being carried on in a desultory fashion for seven years. At the end of this period the citizens of Capua and Valerii made an attack upon the Roman camp, and inflicted a signal defeat upon the besiegers. M. Furius Camillus was then appointed dictator, and a determined attempt was made to end the siege, with the result that Veii fell B.C. 393. Rome's greatest rival in Italy was thus destroyed.
