Aemilius would hold the imperium for a second time in 405 BC, this time as his first term as consular tribune. He shared the office with five others, Titus Quinctius Capitolinus Barbatus, Quintus Quinctius Cincinnatus, Gaius Julius Iulus, Aulus Manlius Vulso Capitolinus and Lucius Furius Medullinus, of which all were former consulars with the exception of Manlius. The consulars saw success against the Veii and began the so-called "siege of Veii" which would last for ten years.
