Off Anjediva he came on the Kempsant's grabs plundering a ship, which he rescued.

One of the grabs was taken and another driven ashore; and so he was gratified with a small success over his inveterate enemies, as he bid farewell to the Indian coast.
As soon as Matthews had returned to Bombay, after the Alibagh fiasco, he applied himself to what, to him, was the principal reason for his coming to India, viz.

private trade.

For the Company's interests he did not care a button; in fact, anything that injured the Company found an advocate in him.

As for the pirates, if they did not come in his way, he was not going to trouble himself much about them.
