The English Assume the Offensive.in July, 1814, the British troops in the first instance being obliged to fall back: this was on the 5th. Their triumph, however, was of brief duration. Veteran troops, who had served under Wellington in Spain, had meanwhile arrived at Quebec; General Drummond arrested the further retreat of Riall's division, and a decisive battle ensued, which terminated in the defeat of the Americans, who were obliged to retire with precipitation beyond the Chippewa.

It appears to have been General Ross's first intention to return to his ships after laying the capital under contribution; but the Americans having fired upon the bearer of the flag of truce who was sent forward with the conditions, all thoughts of an arrangement were
