A Roman history site. Includes a section on Augustus and eventually a database of quotes.
But then things turned nasty in 51 BC when Caesar's governorship of Gaul was revoked by the senate. This left Caesar hanging high and dry, needing to fear prosecution for past irregularities once he returned to Rome.
For months on end there was diplomatic to'ing and thro'ing with Caesar remaining in Gaul, until he lost patience with the niceties of political life. In 49 BC Caesar crossed the Rubicon, the demarcation line between his province and Italy. He marched on Rome at the head of his battle-hardened army, where he met little resistance.
