Operations were recommenced early in the spring of 1814. Lieut.-Colonel Williams, with 1,500 British, having taken post at La Colle, on the river Richelieu. Wilkinson, who had upwards of 4,000 men at Plattsburg, determined to attack them. On the 30th of March, he completely invested a large mill, which the British had converted into a fortress. All his attempts to carry it were, however, fruitless. Major Handcock even made two attacks on the artillery posted in a wood, though without success. The American general finally gave up the undertaking, and fell back upon Plattsburg. In the beginning of May the British gained another advantage, carrying, though with some loss, the fort of Oswego, where they captured a considerable quantity of ammunition and stores. The main effort of the Americans during this campaign was made on the Niagara frontier, where about 5,000 men were placed under Major-General Brown, an officer who had distinguished himself on several occasions. On the 3d of July, he crossed and summoned Fort Erie, which, with its garrison of 170, immediately surrendered. He then marched towards Chippeway, and beat at Street’s Creek the advanced guard of Major-General Riall, which had endeavoured to stop his progress. The English general was then obliged to retreat to Fort George, and thence in the direction of Burlington Heights. Brown hereupon laid siege to the fort, but finding it stronger than he expected, and being disappointed of assistance from Sackett’s Harbour, he fell back upon Chippeway. General Riall, on his part, having received some reinforcements, advanced; the armies came close to each other, and on the 25th the republicans commenced the attack. The battle of Lundy’s Lane was fought long, obstinately, and with various fortune; a great part of it amid thick darkness, which caused several strange mistakes. The American general and his second in command were wounded; and Riall, on the other side, was taken prisoner. By a singular accident, in the midst of the conflict, Lieut.-General Drummond arrived with a reinforcement from York, which restored the battle. Both sides claim a dearly-bought victory; but the real issue seems clearly indicated by the retreat of the Americans to Fort Erie. On the night of the 14th of August, Drummond made an attack on the place in two divisions; but his men, in both cases, were repulsed with very severe loss.
