During his reign the Arabs made a fresh bid to establish their supremacy over Saurashtra.
In 756, the Arab governor of Sindh sent a naval fleet against the Saindhavas.
A Saindhava inscription relates that Agguka I inflicted a disastrous defeat on the Arab naval fleets which forced the Arabs to withdraw.
After this the Caliph Al-Mahdi gave up the project of conquering any part of India through the Navy.
In the Saindhava inscription he was titled as Samudradhipati or Master of the western sea.
