Original prompt & settings (JSON) ↗Almost every senior officer abandoned Sulla rather than lead an army against their own country. Appian says a single quaestor stayed with him.
88 BCE: six legions turn toward Rome
A popular law sponsored by the tribune Publius Sulpicius transferred the command against Mithridates VI from the consul Lucius Cornelius Sulla to Gaius Marius. In 88 BCE Sulla returned to his army near Capua and led six legions toward Rome.
Almost none of his senior officers would go with him; Appian says one quaestor stayed. The soldiers, who feared losing a lucrative eastern campaign, did not refuse.
A battle near the Esquiline Forum
Sulla and his fellow consul Quintus Pompeius Rufus occupied several approaches to the city. Sulla's troops entered while residents threw missiles from the rooftops, until he threatened to burn their houses.
His army then fought forces hastily assembled by Marius and Sulpicius near the Esquiline Forum. Appian calls it Rome's first regular battle fought with trumpets and military standards rather than a street clash.
The morning after
Marius, Sulpicius and their supporters fled. Sulla posted guards, restrained looting — publicly punishing some of his own soldiers for it on the Via Sacra — and the next morning used his military control of the city to annul Sulpicius's measures and have about twelve opponents declared public enemies.
The defensible claim about this is narrower than "first general in history to march on Rome": he was the first Roman commander to seize the city with a Roman citizen army in the Republic's civil conflicts. His dictatorship and reform program followed his second conquest of Rome in 82 BCE.
As for when in 88 BCE: no ancient source supplies a day, and a recent scholarly reconstruction places the march in July or August.

What the sources leave uncertain
- The year 88 BCE is secure, but no ancient source supplies a precise day. A recent scholarly reconstruction places the march in July or August.
- The surviving continuous narratives, principally Appian and Plutarch, were written centuries later and may preserve pro-Sullan traditions.
- Some details of the political measures attributed to Sulla immediately after the 88 seizure are disputed because ancient accounts can blur them with his much larger reform program of 82–81 BCE.
