The great naval preparations of England were not yet complete, but single British men-of-war were now frequently seen off the Atlantic coast of the United States. No American vessels had been captured by these since the message of the Syndicate to the Dominion of Canada and the British Government. But one good reason for this was the fact that it was very difficult now to find upon the Atlantic ocean a vessel sailing under the American flag. As far as possible these had taken refuge in their own ports or in those of neutral countries. At the mouth of Delaware Bay, behind the great Breakwater, was now collected a number of coastwise sailing-vessels and steamers of various classes and sizes; and for the protection of these maritime refugees, two vessels of the United States navy were stationed at this point. These were the Lenox and Stockbridge, two of the finest cruisers in the service, and commanded by two of the most restless and bravest officers of the American navy. The appearance, early on a summer morning, of a large British cruiser off the mouth of the harbour, filled those two commanders with uncontrollable belligerency. That in time of war a vessel of the enemy should be allowed, undisturbed, to sail up and down before an American harbour, while an American vessel filled with brave American sailors lay inside like a cowed dog, was a thought which goaded the soul of each of these commanders. There was a certain rivalry between the two ships; and, considering the insult offered by the flaunting red cross in the offing, and the humiliating restrictions imposed by the Naval Department, each commander thought only of his own ship, and not at all of the other. It was almost at the same time that the commanders of the two ships separately came to the conclusion that the proper way to protect the fleet behind the Breakwater was for his vessel to boldly steam out to sea and attack the British cruiser. If this vessel carried a long-range gun, what was to hinder her from suddenly running in closer and sending a few shells into the midst of the defenceless merchantmen? In fact, to go out and fight her was the only way to protect the lives and property in the harbour. It was true that one of those beastly repellers was sneaking about off the cape, accompanied, probably, by an underwater tongs-boat. But as neither of these had done anything, or seemed likely to do anything, the British cruiser should be attacked without loss of time.
