century. The coins of this type reappear in the second decade of the 5th century, and are dated in the Gupta era, which suggests that Chandragupta subjugated the Western Kshatrapas. The exact date of Chandragupta's victory is not known, but it can be tentatively dated to sometime between 397 and 409. The last of the 4th century Kshatrapa coins - that of Rudrasimha III - can be dated to the Shaka year 310 or 319 (the coin legend is partially lost), that is 388 or 397. Chandragupta's coins, dated to 409, are similar to the Kshtrapa coins, with the Shakas' Buddhist vihara symbol replaced by the Gupta symbol of Garuda. Literary evidence also corroborates Chandragupta's victory over the Western Kshatrapas. The Sanskrit play Devichandraguptam, whose historicity is disputed, narrates that Chandragupta's elder brother Ramagupta agreed to surrender his queen Dhruvadevi to a Shaka chief when besieged, but Chandragupta went to the enemy camp disguised as the queen, and killed the Shaka chief. Chandragupta bore the title Vikramaditya, and several Indian legends talk of king Vikramaditya who defeated the Shakas. Several modern scholars have theorised that these legends may be based on Chandragupta's victory over the Shakas. As a result of his victory over the Western Kshatrapas, Chandragupta must have extended his empire up to the Arabian Sea coast in present-day Gujarat. Other military victories The iron pillar of Delhi contains an inscription of a king called "Chandra". Modern scholars generally identify this king with Chandragupta II, although this cannot be said with complete certainty. While alternative identifications have been proposed, there is strong evidence for identifying Chandra of the iron pillar inscription as Chandragupta II: Chandragupta's coins refer to him as "Chandra". According to the iron pillar inscription, Chandra was a devotee of Vishnu. Chandragupta was also a Vaishnavite, and is described as a Bhagvata (devotee of Vishnu) in the Gupta records. The iron pillar is said to have been set up by king Chandra in honour of Vishnu, on a hill named Vishnu-pada, but the king seems to have died shortly before the inscription was engraved, as the inscription states that "the king has quit the earth and gone to the other world". A similar Vishnu-dhvaja (flagpole in honour of Vishnu) was set up the Gupta emperor Skandagupta (a grandson of Chandragupta) after the death of his father Kumaragupta I. According to his Udayagiri inscription, Chandragupta went on a
