I got curious about caesar and looked on Wikipedia. It says that he chased him all across Europe once then got caught up in Egypt and then Murderd him in Africa. Is this true? Were Roman roads that good that it stretched the whole continent?
Not Pompey himself, but Pompeian forces were scattered across the Mediterranean. During his long career Pompey had crossed the Med several times and was the patron of a number of Eastern kings. On top of that Pompey had control of the Governorship of both Spain and Africa (meaning more or less modern Tunisia).
When Caesar crossed the Rubicon, Pompey and most of the senate fled to Greece where they started raising an army from Pompey’s Eastern clients. That left Caesar in control of Italy, Illyricum, and Gaul with Pompey in control of Spain, Africa, Greece, Asia Minor, Syria, and a strong friendship with Egypt. In other words Caesar was outnumbered and surrounded.
So Caesar after securing Italy, struck to Spain to defeat Pompey’s forces there in summer of 49, thus neutralizing Pompey’s Spanish legions. Pompey himself stayed in Greece. However while Caesar was in Spain and Pompey was in Greece, their forces were fighting in Africa, as Gaius Scribonius Curio and Publius Attius Varus fought on behalf of their patrons. The Pompeians won that. but the fighting tied them in place keeping them from hitting Caesarian forces elsewhere
Caesar crossed the Adriatic in early 48 fighting and eventually defeating Pompey himself in Greece. From there Pompey fled to Egypt, where he was killed by the Ptolemies. Caesar then spent the rest of 48 and 47 engaged in the Ptolemaic civil war, and fighting Pompey’s allies in Syria and Asia. In 46 he finally went to Africa to defeat the Pompey forces in Africa, and in 45 he returned to Spain to fight Pompey’s sons.
Caesar fought Pompean forces all across the Mediterranean. But there were only two engagements between Pompey and Caesar, and both of them were in Greece.
As to roads. The Roman roads were quite good. But the Civil War extended into areas beyond where significant roads were built. And much of the movement of troops was carried by ship. Plus while Caesar went everywhere: Italy, Spain, Italy, Greece, Egypt, Syria, Asia, Italy, Africa, Italy, Spain, and back to Italy; he also took four years to do so.
