Pompeius obtained neither free control over the treasury, nor legions and ships of his own, nor even an authority superior to that of the governors; but they contented themselves with granting to him, for the purpose of his organizing due supplies for the capital, considerable sums, fifteen adjutants, and in allaffairs elating to the supply of grain full proconsular power throughout the Roman dominions for the next five years, and with having this decree confirmed by the burgesses.

There were many different reasons which led to this alteration, almost equivalent to a rejection, of the original plan: a regard to Caesar, with reference to whom the most timid could not but have the greatest scruples in investing his colleague not merely with equal but with superior authority in Gaul itself; the concealed opposition of Pompeius' hereditary enemy and reluctant ally Crassus, to whom Pompeius himself attributed or professed to attribute primarily the failure of his plan; the antipathy of the republican opposition in the senate to any decree which really or nominally enlarged the authority of the regents; lastly and mainly, the incapacity of Pompeius himself, who even after having been compelled to act could not prevail on himself to acknowledge his own action, but chose always to bring forward his real design as it were in incognito by means of his friends, while he himself in his well-known modesty declared his willingness to be content with even less. No wonder that they took him at his word, and gave him the less.

Pompeius was nevertheless glad to have found at any rate a serious employment, and above all a fitting pretext for leaving the capital. He succeeded, moreover, in providing it with ampler and cheaper supplies, although not without the provinces severely feeling the reflex effect. But he had missed his real object; the proconsular title, which he had a right to bear in all the provinces, remained an empty name, so long as he had not troops of his own at his disposal. Accordingly he soon afterwards got a second proposition made to the senate, that it should confer on him the charge of conducting back the expelled king of Egypt, if necessary by force of arms, to his home. But the more that his urgent need of the senate became evident, the senators received his wishes with a less pliant and less respectful spirit. It was immediately discovered in the Sibylline oracles that it was impious to send a Roman army to Egypt; whereupon the pious senate almost unanimously resolved to abstain from armed intervention. Pompeius was already so humbled, that he would have accepted the mission even without an army; but in his incorrigible dissimulation he left this also to be declared merely by his friends, and spoke and voted for the despatch of another senator. Of course the senate rejected a proposal which wantonly risked a life so precious to his country; and the ultimate issue of the endless discussions was the resolution not to interfere in Egypt at all (Jan. 698).

These repeated repulses which Pompeius met with in the senate and, what was worse, had to acquiesce in without retaliation, were naturally regarded - come from what side they would - by the public at large as so many victories of the republicans and defeats of the regents generally; the tide of republican opposition was accordingly always on the increase. Already the elections for 698 had gone but partially according to the minds of the dynasts; Caesar's candidates for the praetorship, Publius Vatinius and Gaius Alfius, had failed, while two decided adherents of the fallen government, Gnaeus Lentulus Marcellinus and Gnaeus Domitius Calvinus, had been elected, the former as consul, the latter as praetor.

But for 699 there even appeared as candidate for the consulship Lucius Domitius Ahenobarbus, whose election it was difficult to prevent owing to his influence in the capital and his colossal wealth, and who, it was sufficiently well known, would not be content with a concealed opposition. The comitia thus rebelled; and the senate chimed in. It solemnly deliberated over an opinion, which Etruscan soothsayers of acknowledged wisdom had furnished respecting certain signs and wonders at its special request. The celestial revelation announced that through the dissension of the upper classes the whole power over the army and treasure threatened to pass to one ruler, and the state to incur loss of freedom - it seemed that the gods pointed primarily at the proposal of Gaius Messius. The republicans soon descended from heaven to earth. The law as to the domain of Capua and the other laws issued by Caesar as consul had been constantly described by them as null and void, and an opinion had been expressed in the senate as early as Dec. 697 that it was necessary to cancel them on account of their informalities. On the 6th April 698 the consular Cicero proposed in a full senate to put the consideration of the Campanian land distribution in the order of the day for the 15th May. It was the formal declaration of war; and it was the more significant, that it came from the mouth of one of those men who only show their colours when they think that they can do so with safety. Evidently the aristocracy held that the moment had come for beginning the struggle not with Pompeius against Caesar, but against the tyrannis generally. What would further follow might easily be seen. Domitius made no secret that he intended as consul to propose to the burgesses the immediate recall of Caesar from Gaul. An aristocratic restoration was at work; and with the attack on the colony of Capua the nobility threw down the gauntlet to the regents.

Caesar, although receiving from day to day detailed accounts of the events in the capital and, whenever military considerations allowed, watching their progress from as near a point of his southern province as possible, had not hitherto, visibly at least interfered in them. But now war had been declared against him as well as his colleague, in fact against him especially; he was compelled to act, and he acted quickly. He happened to be in the very neighbourhood; the aristocracy had not even found it advisable to delay the rupture, till he should have again crossed the Alps. In the beginning of April 698 Crassus left the capital, to concert the necessary measures with his more powerful colleague; he found Caesar in Ravenna. Thence both proceeded to Luca, and there they were joined by Pompeius, who had departed from Rome soon after Crassus (11 April), ostensibly for the purpose of procuring supplies of grain from Sardinia and Africa. The most noted adherents of the regents, such as Metellus Nepos the proconsul of Hither Spain, Appius Claudius the propraetor of Sardinia, and many others, followed them; a hundred and twenty lictors, and upwards of two hundred senators were counted at this conference, where already the new monarchical senate was represented in contradistinction to the republican.

In every respect the decisive voice lay with Caesar. He used it to re-establish and consolidate the existing joint rule on a new basis of more equal distribution of power of most importance in a military point of view, next to that of the two Gauls, were assigned to his two colleagues - that of the two Spains to Pompeius, that of Syria to Crassus; and these offices were to be secured to them by decree of the people for five years (700-704), and to be suitably provided for in a military and financial point of view. On the other hand Caesar stipulated for the prolongation of his command, which expired with the year 700, to the close of 705, as well as for the prerogative of increasing his legions to ten and of charging the pay for the troops arbitrarily levied by him on the state-chest. Pompeius and Crassus were moreover promised a second consulship for the next year (699) before they departed for their governorships, while Caesar kept it open to himself to administer the supreme magistracy a second time after the termination of his governorship in 706, when the ten years' interval legally requisite between two consulships should have in his case elapsed. The military support, which Pompeius and Crassus required for regulating the affairs of the capital all the more that the legions of Caesar originally destined for this purpose could not now be withdrawn from Transalpine Gaul, was to be found in new legions, which they were to raise for the Spanish and Syrian armies and were not to despatch from Italy to their several destinations until it should seem to themselves convenient to do so. The main questions were thus settled; subordinate matters, such as the settlement of the tactics to be followed against the opposition in the capital, the regulation of the candidatures for the ensuing years, and the like, did not long detain them. The great master of mediation composed the personal differences which stood in the way of an agreement with his wonted ease, and compelled the most refractory elements to act in concert.
