After the reduction of Bazira Alexander marched towards the Indus and received the submission of Peukelaotis, which was then the capital of what is now, roughly speaking, the Peshawur district. The site of this ancient capital appears to be ascertained beyond doubt, and we must regard it as fixed near Charsadda, about 17 miles north-east (not north-west as M'Crindle has it) from Peshawur. From this place Alexander marched to Embolina, which is said to be a city close adjoining the rock of Aornos. On the route thither he is said by Arrian to have taken "many other small towns seated upon that river," _i.e_. the Indus; two princes of that province, Cophæus and Assagetes, accompanying him. This sufficiently indicates that his march must have been up the right bank of the Indus, which would be the natural route for him to follow. Arrived at Embolina, he arranged for a base of supplies at that point, and then, with "Archers, Agrians, Cænus' Troop" and the choicest, best armed, and most expeditious foot out of the whole army, besides 200 auxiliary horse and 100 equestrian archers, he marched towards the "rock" (8 miles distant), and on the first day chose a place convenient for an encampment. The day after, he pitched his tents much higher. The ancient Embolina may not be the modern Amb, but Amb undoubtedly is an extremely probable site for such a base of supplies to be formed, whether the final objective were Mahaban or any place (as suggested by Stein) higher up the river. The fact that there is a similarity in the names Amb and Embolina need not militate against the adoption of the site of Amb as by far the most probable that any sagacious military commander would select. A mere resemblance between the ancient and modern names of places may, of course, be most deceptive. On the other hand it is often a most valuable indication, and one certainly not to be neglected. Place-names last with traditional tenacity in the East, and obscured as they certainly would be by Greek transliteration (after all, not worse than British transliteration), they still offer a chance of identifying old positions such as nothing else can offer excepting accurate topographical description. Once again, if Embolina were not Amb it certainly ought to have been.
