Certainly the success of this plan depended on Pompeius being good- natured enough to let Caesar still obtain the consulship for 706 assured to him at Luca; but, even if it failed, it would be always of advantage for Caesar to have given practical and repeated evidence of the most yielding disposition. On the one hand time would thus be gained for attaining his object meanwhile in Gaul; on the other hand his opponents would be left with the odium of initiating the rupture and consequently the civil war-- which was of the utmost moment for Caesar with reference to the majority of the senate and the party of material interests, and more especially with reference to his own soldiers.
On these views he acted. He armed certainly; the number of his legion was raised through new levies in the winter of 702-703 to eleven, including that borrowed from Pompeius. But at the same time he expressly and openly approved of Pompeius' conduct during the dictatorship and the restoration of order in the capital which he had effected, rejected the warnings of officious friends as calumnies, reckoned every day by which he succeeded in postponing the catastrophe a gain, overlooked whatever could be overlooked and bore whatever could be borne-- immoveably adhering only to the one decisive demand that, when his governorship of Gaul came to an end with 705, the second consulship, admissible by republican state-law and promised to him according to agreement by his colleague, should be granted to him for the year 706.
