In the events of the present campaign the enemy, with all his augmented means and wanton use of them, has little ground for exultation, unless he can feel it in the success of his recent enterprises against this metropolis and the neighboring town of Alexandria, from both of which his retreats were as precipitate as his attempts were bold and fortunate. In his other incursions on our Atlantic frontier his progress, often checked and chastised by the martial spirit of the neighboring citizens, has had more effect in distressing individuals and in dishonoring his arms than in promoting any object of legitimate warfare; and in the two instances mentioned, however deeply to be regretted on our part, he will find in his transient success, which interrupted for a moment only the ordinary public business at the seat of Government, no compensation for the loss of character with the world by his violations of private property and by his destruction of public edifices protected as monuments of the arts by the laws of civilized warfare.

On our side we can appeal to a series of achievements which have given new luster to the American arms. Besides the brilliant incidents in the minor operations of the campaign, the splendid victories gained on the Canadian side of the Niagara by the American forces under Major-General Brown and Brigadiers Scott and Gaines have gained for these heroes and their emulating companions the most unfading laurels, and, having triumphantly tested the progressive discipline of the American soldiery, have taught the enemy that the longer he protracts his hostile efforts the more certain and decisive will be his final discomfiture.

On our southern border victory has continued also to follow the American standard. The bold and skillful operations of Major-General Jackson, conducting troops drawn from the militia of the States least distant, particularly of Tennessee, have subdued the principal tribes of hostile savages, and, by establishing a peace with them, preceded by recent and exemplary chastisement, has best guarded against the mischief of their cooperation with the British enterprises which may be planned against that quarter of our country. Important tribes of Indians on our northwestern frontier have also acceded to stipulations which bind them to the interests of the United States and to consider our enemy as theirs also.

In the recent attempt of the enemy on the city of Baltimore, defended by militia and volunteers, aided by a small body of regulars and seamen, he was received with a spirit which produced a rapid retreat to his ships, whilst a concurrent attack by a large fleet was successfully resisted by the steady and well-directed fire of the fort and batteries opposed to it.

In another recent attack by a powerful force on our troops at Plattsburg, of which regulars made a part only, the enemy, after a perseverance for many hours, was finally compelled to seek safety in a hasty retreat, with our gallant bands pressing upon him.

On the Lakes, so much contested throughout the war, the great exertions for the command made on our part have been well repaid. On Lake Ontario our squadron is now and has been for some time in a condition to confine that of the enemy to his own port, and to favor the operations of our land forces on that frontier.

A part of the squadron on Lake Erie has been extended into Lake Huron, and has produced the advantage of displaying our command on that lake also. One object of the expedition was the reduction of Mackinaw, which failed with the loss of a few brave men, among whom was an officer justly distinguished for his gallant exploits. The expedition, ably conducted by both the land and the naval commanders, was otherwise highly valuable in its effects.

On Lake Champlain, where our superiority had for some time been undisputed, the British squadron lately came into action with the American, commanded by Captain Macdonough. It issued in the capture of the whole of the enemy's ships. The best praise for this officer and his intrepid comrades is in the likeness of his triumph to the illustrious victory which immortalized another officer and established at a critical moment our command of another lake.

On the ocean the pride of our naval arms had been amply supported. A second frigate has indeed fallen into the hands of the enemy, but the loss is hidden in the blaze of heroism with which she was defended. Captain Porter, who commanded her, and whose previous career had been distinguished by daring enterprise and by fertility of genius, maintained a sanguinary contest against two ships, one of them superior to his own, and under other severe disadvantages, till humanity tore down the colors which valor had nailed to the mast. This officer and his brave comrades have added much to the rising glory of the American flag, and have merited all the effusions of gratitude which their country is ever ready to bestow on the champions of its rights and of its safety.

Two smaller vessels of war have also become prizes to the enemy, but by a superiority of force which sufficiently vindicates the reputation of their commanders, whilst two others, one commanded by Captain Warrington, the other by Captain Blakely, have captured British ships of the same class with a gallantry and good conduct which entitle them and their companions to a just share in the praise of their country.
