Although wealth and luxury were almost unknown among them, the governing class in St. Peter's Port formed an extremely aristocratic and exclusive set, vying in dress, manners, and language with society of the same rank in England. Their children were frequently sent there to school, and as their sons grew up, commissions in the English army and navy were eagerly sought, and in many a hard-fought battle on land and sea, the men of Guernsey have won renown. It was not the gentler born alone that were trained to arms. By the law of the island, every male inhabitant between the age of sixteen and thirty-three was bound to render "man service to the Crown," and in the stormy days of the latter half of the eighteenth century {5} and the beginning of the nineteenth, they were often called on to take their share in the king's wars. [Sidenote: The Brocks of Guernsey] For generations the Brocks had lived in St. Peter's Port, and as Guernsey chronicles go back to legendary times, the story that they were descended from one Sir Hugh Brock who came there in the fourteenth century is perhaps a true one. It seems that in the reign of Edward III. an English knight of that name was keeper of the castle of Derval, in Brittany. When the French overran that country this castle was besieged by the Duke of Bourbon, the Earls of Alençon and Perche, and a gallant array of the chivalry of France. Now Sir Hugh Brock's cousin, Sir Robert Knolles, who was governor of the duchy of Brittany, was also at that time besieged in Brest by the famous Bertrand du Guesclin. He succeeded in driving off his assailants, and then marched to the relief of his cousin, Sir Hugh, who was on the point of surrendering when the timely succour arrived. The English were, however, soon after driven out of France by the valiant du Guesclin, and as Guernsey lies directly between the coast of Brittany and England it is not improbable that this same Sir Hugh or some of his family settled there.
