The second great Yavana invasion had thus passed beyond the bounds of Alexander's Indian realm in two directions—beyond the Beās eastwards, and beyond the Indus delta southwards. But it is doubtful if the successors of Demetrius, Apollodotus, and Menander exercised any permanent sway over the very wide expanse of territory indicated in Strabo's *Geography*. It is more likely that most of the princes whose coins we possess ruled over various kingdoms in the northern region of this area, that is to say, in the Kābul valley, in the North-Western Frontier Province, and in the northern districts of the Punjab. It is certain however that the military expeditions of the Yavanas were by no means confined within these limits. One such incursion which broke through the Delhi passage and penetrated the Midland Country as far as Pāṭaliputra (Patna) is described in the Yuga Purāṇa, one of the chapters of the Gārgī Saṃhitā.
