While admiral Russel asserted the British dominion in the Mediterranean, the French coasts were again insulted in the channel by a separate fleet under the command of lord Berkeley of Stratton, assisted by the Dutch admiral Allemonde. On the fourth day of July they anchored before St. Maloes, which they bombarded from nine ketches covered by some frigates, which sustained more damage than was done to the enemy. On the sixth, Granville underwent the same fate, and then the fleet returned to Portsmouth. The bomb vessels being refitted, the fleet sailed round to the Downs, where four hundred soldiers were embarked for an attempt upon Dunkirk, under the direction of Meesters the famous Dutch engineer, who had prepared his infernals and other machines for the service. On the first day of August the experiment was tried without success. The bombs did some execution; but two smoke ships miscarried. The French had secured the Ris-bank and wooden forts with piles, bombs, chains, and floating batteries, in such a manner that the machine-vessels could not approach near enough to produce any effect. Besides, the councils of the assailants were distracted by violent animosities. The English officers hated Meesters, because he was a Dutchman, and had acquired some credit with the king; he on the other hand treated them with disrespect. He retired with his machines in the night, and refused to co-operate with lord Berkeley in his design upon Calais, which was now put in execution. On the sixteenth he brought his batteries to bear upon this place, and set fire to it in different quarters; but the enemy had taken such precautions as rendered his scheme abortive.
