The summer of 1778 thus turned out badly for Washington. Help from France which had aroused such joyous hopes in America had achieved little and the allies were hurling reproaches at each other. French and American soldiers had riotous fights in Boston and a French officer was killed. The British, meanwhile, were landing at small ports on the coast, which had been the haunts of privateers, and were not only burning shipping and stores but were devastating the country with Loyalist regiments recruited in America. The French told the Americans that they were expecting too much from the alliance, and the cautious Washington expressed fear that help from outside would relax effort at home. Both were right. By the autumn the British had been reinforced and the French fleet had gone to the West Indies. Truly the mountain in labor of the French alliance seemed to have brought forth only a ridiculous mouse. None the less was it to prove, in the end, the decisive factor in the struggle. The alliance with France altered the whole character of the war, which ceased now to be merely a war in North America. France soon gained an ally in Europe. Bourbon Spain had no thought of helping the colonies in rebellion against their king, and she viewed their ambitions to extend westward with jealous concern, since she desired for herself both sides of the Mississippi. Spain, however, had a grievance against Britain, for Britain would not yield Gibraltar, that rocky fragment of Spain commanding the entrance to the Mediterranean which Britain had wrested from her as she had wrested also Minorca and Florida. So, in April, 1779, Spain joined France in war on Great Britain. France agreed not only to furnish an army for the invasion of England but never to make peace until Britain had handed back Gibraltar. The allies planned to seize and hold the Isle of Wight. England has often been threatened and yet has been so long free from the tramp of hostile armies that we are tempted to dismiss lightly such dangers. But in the summer of 1779 the danger was real. Of warships carrying fifty guns or more France and Spain together had one hundred and twenty-one, while Britain had seventy. The British Channel fleet for the defense of home coasts numbered forty ships of the line while France and Spain together had sixty-six. Nor had Britain resources in any other quarter upon which she could readily draw. In the West Indies she had twenty-one ships of the line while France had twenty-five. The British could not find comfort in any supposed superiority in the structure of their ships. Then and later, as Nelson admitted when he was fighting Spain, the Spanish ships were better built than the British.
