In presence of the regents on the one hand, and on the other hand of this indolent majority, which desired peace above all things and at any price, and was averse to any decided action and most of all to a decided rupture with one or other of the regents, the only possible course for the Catonian party to obtain a restoration of the old rule lay in a coalition with the less dangerous of the rulers.

If Pompeius acknowledged the oligarchic constitution and offered to fight for it against Caesar, the republican opposition might and must recognize him as its general, and in alliance with him compel the timid majority to a declaration of war.
That Pompeius was not quite in earnest with his fidelity to the constitution, could indeed escape nobody; but, undecided as he was in everything, he had by no means arrived like Caesar at a clear and firm conviction that it must be the first business of the new monarch to sweep off thoroughly and conclusively the oligarchic lumber.

At any rate the war would train a really republican army and really republican generals; and, after the victory over Caesar, they might proceed with more favourable prospects to set aside not merely oneof the monarchs, but the monarchy itself, which was in the course of formation.

Desperate as was the cause of the oligarchy, the offer of Pompeius to become its ally was the most favourable arrangement possible for it.
Their League with Pompeius The conclusion of the alliance between Pompeius and the Catonian party was effected with comparative rapidity.

Already during the dictatorship of Pompeius a remarkable approximation had taken place between them.
The whole behaviour of Pompeius in the Milonian crisis, his abrupt repulse of the mob that offered him the dictatorship, his distinct declaration that he would accept this office only from the senate, his unrelenting severity against disturbers of the peace of every sort and especially against the ultra-democrats, the surprising complaisance with which he treated Cato and those who shared his views, appeared as much calculated to gain the men of order as they were offensive to the democrat Caesar.
On the other hand Cato and his followers, instead of combating with their wonted sternness the proposal to confer the dictatorship on Pompeius, had made it with immaterial alterations of form their own; Pompeius had received the undivided consulship primarily from the hands of Bibulus and Cato.
