But the privateers' men attacked a boat's crew of the Alarm, were beaten, raised a riot, and attacked a Welsh lady's house where English officers were at a party; after which, with pistol shots and climbing over back walls, the English, by help of a few Spanish gentlemen, escaped, leaving behind them their surgeon severely wounded.

Vaughan would chastise the rascally French who had attacked his men.
