This state of things was however not to last long. Towards the end of February, 1653, Blake put to sea with nearly eighty ships, and on the 25th off Portland met Tromp at the head of a force nearly equal to his own in number. But the Dutch admiral was convoying more than 150 merchantmen and he had moreover been at sea without replenishment of stores ever since the fight at Dungeness, while the English had come straight from port. The fight, which on the part of the Dutch consisted of strong rear-guard actions, had lasted for two whole days, when Tromp found that his powder had run out and that on the third day more than half his fleet were unable to continue the struggle. But, inspiring his subordinates De Ruyter, Evertsen and Floriszoon with his own indomitable courage, Tromp succeeded by expert seamanship in holding off the enemy and conducting his convoy with small loss into safety. Four Dutch men-of-war were taken and five sunk; the English only lost two ships.
Meanwhile both nations had been getting sick of the war. The Dutch were suffering terribly from the serious interference with their commerce and carrying trade and from the destruction of the important fisheries industry, while the English on their side were shut out from the Baltic, where the King of Denmark, as the ally of the United Provinces, had closed the Sound, and from the Mediterranean, where Admiral van Galen, who lost his life in the fight, destroyed a British squadron off Leghorn (March 23). In both countries there was a peace party. Cromwell had always wished for a closer union with the United Provinces and was averse to war. In the Dutch republic the States party, especially in Holland the chief sufferer by the war, was anxious for a cessation of hostilities; and it found its leader in the youthful John de Witt, who on the death of Adrian Pauw on February 21, 1653, had been appointed council-pensionary.
