The dashing hero of this book, Terence O'Connor, was the hero of Mr. Henty's previous book, "With Moore at Corunna," to which this is really a sequel. He is still at the head of the "Minho" Portuguese regiment. Being detached on independent and guerilla duty with his regiment, he renders invaluable service in gaining information and in harassing the French. His command, being constantly on the edge of the army, is engaged in frequent skirmishes and some most important battles.
