It is almost certain that Chandragupta had other successful military
operations to this credit the basis of refernces mentioned in Virasena's
Udaygiri cave inscription that the king set out 'to conquer the whole
world', and in Sanchi inscription in which one of Chandragupta's
military officer is said to have obtained great glory by winning many
battles. But we have no definite and detailed information regarding the
nature and result of these campaigns.
The military exploits of a king called Chandra are mentioned in Mahrauli
iron Pillar inscription. It is stated in the inscription that the king
defeated a confederacy of hostile chiefs in Vanga and having crossed in
warfare the seven months of the river Sindhu, conquered the Vahilkas.
Vanga denotes Eastern Bengal, verynearly the same country as Samatata
which is included in the tributary frontier states of Samudragupta. It
is possible that some of the rulers refused to accept Chandragupta's
authority and consequently the latter had to fight against them. The
compaign resulted in the inconporation of the province in the Gutpta
empire.
Vahilka, according to Dr. R.C. Majumdar, is almost certainly to be
identified with Balkh (Bactria) beyond the Hindukush mountains. 'Here
too,' the motive of the compaign was probably similar tothat against
eastern Bengal, i.e. either the Kushans who referred to sas
Daivaputra-Shahi - Shahanushani in Allahabad Pillar Inscription had
acknowledged the supremacy of Samudragupta rebelled, or Chandragupta II
wanted to establish his authorirty on a firmer basis'.
Samudragupta had begun the work of conquest. But it was his son who
completed the task and kingdoms on the border but also the territories
ruled by foreign hordes like the Sakas and Kushanas. Chadragupta too the
title of Vikramaditya (Sun of power) and for this tilte he had a better
claim than any other sovereign of northern India. That he was the real
architect of the Gupta empire, there can be no two opinions.
Chadragupta II ruled for nearly 35 years. And he was succeeded by Kumar
Gupta -O in 415 A.D. He, too, ruled the empire for about 40 years.
Details of his reign art not known. However as he, too. Performed the
horse sacrifice, probably he added to his inherited dominions.
