  From the period 52 to 49 BC, trust between Caesar and Pompey disintegrated. In 51 BC, the consul Marcellus proposed recalling Caesar, arguing that his provincia (here meaning "task") in Gaul – due to his victory against Vercingetorix in 52 – was complete; it evidently was incomplete as Caesar was that year fighting the Bellovaci and regardless the proposal was vetoed. That year, it seemed that the conservatives around Cato in the Senate would seek to enlist Pompey to force Caesar to return from Gaul without honours or a second consulship. Cato, Bibulus, and their allies, however, were successful in winning Pompey over to take a hard line against Caesar's continued command.
  
  As 50 BC progressed, fears of civil war grew; both Caesar and his opponents started building up troops in southern Gaul and northern Italy, respectively. In the autumn, Cicero and others sought disarmament by both Caesar and Pompey, and on 1 December 50 BC this was formally proposed in the Senate. It received overwhelming support – 370 to 22 – but was not passed when one of the consuls dissolved the meeting. That year, when a rumour came to Rome that Caesar was marching into Italy, both consuls instructed Pompey to defend Italy, a charge he accepted as a last resort. At the start of 49 BC, Caesar's renewed offer that he and Pompey disarm was read to the Senate and was rejected by the hardliners. A later compromise given privately to Pompey was also rejected at their insistence. On 7 January, his supportive tribunes were driven from Rome; the Senate then declared Caesar an enemy and it issued its senatus consultum ultimum.
  
  There is scholarly disagreement as to the specific reasons why Caesar marched on Rome. A very popular theory is that Caesar was forced to choose – when denied the immunity of his proconsular tenure – between prosecution, conviction, and exile or civil war in defence of his position. Whether Caesar actually would have been prosecuted and convicted is debated. Some scholars believe the possibility of successful prosecution was extremely unlikely. Caesar's main objectives were to secure a second consulship – first mooted in 52 as colleague to Pompey's sole consulship – and a triumph. He feared that his opponents – then holding both consulships for 50 BC – would reject his candidacy or refuse to ratify an election he won. This also was the core of his war justification: that Pompey and his allies were planning, by force if necessary (indicated in the expulsion of the tribunes), to suppress the liberty of the Roman people to elect Caesar and honour his accomplishments.
