Since the events of Dyrrhachium
these lords regarded the triumph of their party as an ascertained fact;
already there was eager strife as to the filling up of Caesar's
supreme pontificate, and instructions were sent to Rome
to hire houses at the Forum for the next elections. When Pompeius
hesitated on his part to cross the rivulet which separated
the two armies, and which Caesar with his much weaker army
did not venture to pass, this excited great indignation; Pompeius,
it was alleged, only delayed the battle in order to rule somewhat longer
over so many consulars and praetorians and to perpetuate his part
of Agamemnon.
Pompeius yielded; and Caesar, who under the impression
that matters would not come to a battle, had just projected
a mode of turning the enemy's army and for that purpose was on the point
of setting out towards Scotussa, likewise arrayed his legions for battle,
when he saw the Pompeians preparing to offer it to him on his bank.
