Trade was flourishing, though the piracies of Sumbhajee Angria, in spite of his feud with Mannajee, caused losses from time to time.

The English ships, better manned and better found, no longer contented themselves with repelling attacks, but boldly cruised in search of Sumbhajee's vessels, capturing them or driving them to seek refuge in their fortified harbours.
To relate in detail all the encounters that took place would be tedious; but some of them may be mentioned, in order to give an idea of the warfare that went on for thirty years after Boone's relinquishment of office.
In October, 1730, intelligence having been received of Angrian gallivats cruising north of Bombay, some Bombay gallivats were sent out, and after a smart action captured three of them, each carrying five guns.

A month later, the _Bombay_ and _Bengal_ galleys were attacked off Colaba by four grabs and fifteen gallivats.

There was a calm at the time: the hostile grabs were towed under the galleys' stern and opened a heavy fire.

The galleys were only able to reply with small arm fire, and suffered severely.
Several attempts to board were repelled, when an unlucky shot exploded two barrels of musket cartridges on board the _Bengal_.
