vowed till the day of his death, that he would invade India once again and
conquer it thoroughly, that the chief officers of his state and commanders
were at war with one another for the division of the Greek empire, that the
triumphant one among them who would ascend the throne at Babylon
would not fail to attack India with an army more powerful than before, and
that the first victims to that aggression would be these very people, if they
remained disunited as separate Rajakas (monarchies) and Prajakas
(republics). But if they availed themselves of this opportunity of the civil
feuds of the Greeks, and they could merge the whole of India into a strong
empire with an efficient administration at the centre, this new Indian
empire, stronger than that of the Greeks, could very easily beat the
Mlenchchas, were they to come once again aggressively. Hence, they said
India should be built into one strong nation!
Invasion of Chandragupta and Chanakya on Magadha
116. Without wasting even a single moment of the golden opportunity of
the Greek internecine wars, Chandragupta and other followers of Chanakya
began openly to raise a powerful army to march first of all against
Magadha, according to Chanakya’s plan of the political revolution. A few
but very telling references to this fact are to be found in the critique named
‘Mahavamsha’. From these and from other sources, it appears that this
invading army of Chandragupta was mainly composed of the soldiers from
Panchanad, the Pauravas and the republics that were inspired with the
preaching of Chanakya for a unitary Indian empire. In order to enlist the
sympathies of the Parvateshwara, i.e. King Paurav, who was a powerful
king in those provinces, Chanakya is said to have met him secretly. As
Alexander’s sway had been completely thrown off from the Indian
territories, King Paurav was no longer a subordinate satrap of the Greeks.
From stray references in some books, it appears that not only King Paurav
offered his support for Chanakya’s cause, but some wealthy people too
helped him actively. Chanakya offered the command of the whole army to
Chandragupta. After establishing their hold on all possible regions of
Panchanad, they marched speedily on Magadha. The Indian populace and
the local powers disgusted with and enraged at the tyrannical and weak rule
of Nanda, and inspired by Chanakya’s ideal of a strong unitary empire of
the whole of India, joined Chandragupta’s army as it marched ahead
fighting.
