On the 21st we saw and chased two sail, off Flamborough Head, the Pallas in the N. E. quarter, while the Bonhomme Richard followed by the Vengeance in the S. W. The one I chased, a brigantine collier in ballast, belonging to Scarborough, was soon taken, and sunk immediately afterward, as a fleet then appeared to the southward. It was so late in the day that I could not come up with the fleet before night; at length, however, I got so near one of them as to force her to run ashore, between Flamborough Head and the Spurn. Soon after I took another, a brigantine from Holland, belonging to Sunderland; and at daylight the next morning, seeing a fleet steering towards me from the Spurn, I imagined them to be a convoy, bound from London for Leith, which had been for some time expected; one of them had a pendant hoisted, and appeared to be a ship of force. They had not, however, courage to come on, but kept back, all except the one which seemed to be armed, and that one also kept to windward (p. 104) very near the land, and on the edge of dangerous shoals, where I could not with safety approach. This induced me to make a signal for a pilot, and soon afterward two pilot boats came off; they informed me that the ship that wore a pendant was an armed merchant ship, and that a king's frigate lay there in sight, at anchor within the Humber, waiting to take under convoy a number of merchant ships bound to the northward. The pilots imagined the Bonhomme Richard to be an English ship of war, and, consequently, communicated to me the private signal which they had been required to make. I endeavoured by this means to decoy the ships out of the port, but the wind then changing, and with the tide becoming unfavourable for them, the deception had not the desired effect, and they wisely put back. The entrance of the Humber is exceedingly difficult and dangerous, and, as the Pallas was not in sight, I thought it not prudent to remain off the entrance; I, therefore, steered out again to join the Pallas off Flamborough Head. In the night we saw and chased two ships until three o'clock in the morning, when, being at a very small distance from them, I made the private signal of recognizance, which I had given to each captain before I sailed from Groaix. One half of the answer only was returned. In this position both sides lay to till daylight, when the ships proved to be the Alliance and the Pallas.
