Sorath was ruled by Chudasama king Ra Mokalasimha. He had to move the capital from Junagadh to Vanthali due to order from the Governor of Gujarat Zafar Khan (grandfather of Ahmad Shah) on behalf of Delhi Sultan Firuz Shah Tughluq. Zafar Khan had occupied his capital Junagadh in 1395-96. In 1414, his son Meliga regained Junagadh and also gave refuge to some of rebels (probably Jhala chief Satrasal). This irked Ahmad Shah and he attacked Sorath. Ahmad Shah won pitched battle at Vanthali in 1413. Later he imposed siege of Junagadh in 1414. Meliga retired to the hill fortress of Girnar. Ahmad Shah, though unable to capture the hill, gained the fortified citadel of Junagaḍh. Finding further resistance vain, the chief tendered his submission, and Junagaḍh was admitted among the tributary states. Several other Sorath chief also submitted. Sayad Abul Khair and Sayad Kasim were left to collect the tribute, and Ahmad Shah returned to Ahmedabad.
