In the spring of 688 Pompeius proceeded to Galatia, to take
the chief command of the troops of Lucullus and to advance
with them into the Pontic territory, whither the Cilician legions
were directed to follow. At Danala, a place belonging to the Trocmi,
the two generals met; but the reconciliation, which mutual friends
had hoped to effect, was not accomplished. The preliminary
courtesies soon passed into bitter discussions, and these
into violent altercation: they parted in worse mood than they had met.
As Lucullus continued to make honorary gifts and to distribute
lands just as if he were still in office, Pompeius declared
all the acts performed by his predecessor subsequent to
his own arrival null and void. Formally he was in the right;
customary tactin the treatment of a meritorious and more than
sufficientlymortified opponent was not to be looked for from him.
