The hotheads cried out for the immediate storming of the fort; but cooler counsels prevailed, and a siege was decided upon. Trenches were dug, the guns in the outlying batteries were turned upon the fort, and the New Englanders sat down to wait until the enemy should be starved out or until re-enforcements might be brought from Boston.

So for three weeks the combatants rested on their arms, glaring at each other over the tops of their breastworks, and now and then exchanging a shot or a casual volley, but doing little in the way of actual hostilities. Provisions were failing the British, and they began to feel that they were in a trap from which they could only emerge through a surrender, when suddenly the situation was changed, and the fortunes of war went against the Americans.

One morning the "Tyrannicide," which was stationed on the lookout down the bay, was seen beating up the river, under a full press of sail. Signals flying at her fore indicated that she had important news to tell. Her anchor had not touched the bottom before a boat pushed off from her side, and made straight for the commodore's flag-ship. Reaching the "Warren," a lieutenant clambered over the side, and saluted Commodore Saltonstall on the quarter-deck.

"Capt. Cathcart's compliments, sir," said he, "and five British men-of-war are just entering the bay. The first one appears to be the 'Rainbow,' forty-four."

Here was news indeed. Though superior in numbers, the Americans were far inferior in weight of metal. After a hasty consultation, it was determined to abandon the siege, and retreat with troops and vessels to the shallow waters of the Penobscot, whither the heavy men-of-war of the enemy would be unable to follow them. Accordingly the troops were hastily re-embarked, and a hurried flight began, which was greatly accelerated by the appearance of the enemy coming up the river.

The chase did not continue long before it became evident the enemy would overhaul the retreating ships. Soon he came within range, and opened fire with his bow-guns, in the hopes of crippling one of the American ships. The fire was returned; and for several hours the wooded shores of the Penobscot echoed and re-echoed the thunders of the cannonade, as the warring fleets swept up the river.

At last the conviction forced itself on the minds of the Americans, that for them there was no escape. The British were steadily gaining upon them, and there was no sign of the shoal water in which they had hoped to find a refuge. It would seem that a bold dash might have carried the day for the Americans, so greatly did they outnumber their enemies. But this plan does not appear to have suggested itself to Capt. Saltonstall, who had concentrated all his efforts upon the attempt to escape. When escape proved to be hopeless, his only thought was to destroy his vessels. Accordingly his flag-ship, the "Warren," was run ashore, and set on fire. The action of the commodore was imitated by the rest of the officers, and soon the banks of the river were lined with blazing vessels. The "Hunter," the "Hampden," and one transport fell into the hands of the British. The rest of the forty-nine vessels—men-of-war, privateers, and transports—that made up the fleet were destroyed by flames.

It must indeed have been a stirring spectacle. The shores of the Penobscot River were then a trackless wilderness; the placid bosom of the river itself had seldom been traversed by a heavier craft than the slender birch-bark canoe of the red man; yet here was this river crowded with shipping, the dark forests along its banks lighted up by the glare of twoscore angry fires. Through the thickets and underbrush parties of excited men broke their way, seeking for a common point of meeting, out of range of the cannon of the enemy. The British, meantime, were striving to extinguish the flames, but with little success; and before the day ended, little remained of the great Massachusetts flotilla, except the three captured ships and sundry heaps of smouldering timber.

The hardships of the soldiers and marines who had escaped capture, only to find themselves lost in the desolate forest, were of the severest kind. Separating into parties they plodded along, half-starved, with torn and rain-soaked clothing, until finally, footsore and almost perishing, they reached the border settlements, and were aided on their way to Boston. The disaster was complete, and for months its depressing effect upon American naval enterprise was observable.

In observing the course of naval events in 1779, it is noticeable that the most effective work was done by the cruisers sent out by the individual States, or by privateers. The United States navy, proper, did little except what was done in European waters by Paul Jones. Indeed, along the American coast, a few cruises in which no actions of moment occurred, although several prizes were taken, make up the record of naval activity for the year.
