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.
