the latter has been built within the mountains on the plain.  Saxa and Norbanus happened to have occupied the shortest path across, therefore Brutus and Cassius did not even try to get through that way, but went around by a longer path,—­the so-called Crenides.[33] Here, too, they encountered a guard, but overpowered it, got inside the mountains, approached the city along the high ground, and there encamped each one apart,—­if we are to follow the story.  As a matter of fact they bivouacked in one spot.  In order that the soldiers might preserve better discipline and be easier to manage, the camp was made up of two separate divisions:  but as all of it, including the intervening space, was surrounded by a ditch and a rampart, the entire circuit belonged to both, and from it they derived safety in common. [-36-] They were far superior in numbers to their adversaries then present and by that means got possession of Symbolon, having first ejected the inhabitants.  In this way they were able to bring provisions from the sea, over a shorter stretch of country, and had only to make a descent from the plain to get them.  For Norbanus and Saxa did not venture to offer them battle with their entire force, though they did send out horsemen to make sorties, wherever opportunity offered.  Accomplishing nothing, however, they were rather careful to keep their camp well guarded than to expose it to danger, and sent in haste for Caesar and Antony.  These leaders on learning that Cassius and Brutus were for some time busy with the Rhodians and the Lycians had thought that their adversaries would have more fighting on their hands there, and so instead of hastening had sent Saxa and Norbanus forward into Macedonia.  On finding out that their representatives were caught they bestowed praise on the Lycians and Rhodians, promising to make them a present of money, and they themselves at once set out from the city.  Both, however, encountered a delay of some time,—­Antony near Brundusium, because blocked by Staius, and Caesar near Rhegium, having first turned aside to meet Sextus, held Sicily and was making an attempt on Italy. [-37-] When it seemed to them to be impossible to dislodge him, and the case of Cassius and Brutus appeared to be more urgent, they left a small part of their army to garrison Italy and with the major portion safely crossed the Ionian sea.  Caesar fell sick and was left behind at Dyrrachium, while Antony marched for Philippi.  For a time he was a source of some strength to his soldiers, but after laying an ambush for some of the opposite party that were gathering grain and failing in his attempt he was no longer of good courage himself.  Caesar heard of it and feared either possible outcome, that his colleague should be defeated in a separate attack or again that he should conquer:  in the former event he felt that Brutus and Cassius would attain power, and in the latter that Antony would have it all himself; therefore he made haste though still unwell.
