So terrible had been the mortality that throughout England there was a lack of hands for field work, crops rotted in the ground because there were none to harvest them, and men able to work demanded twenty times the wages which had before been paid. So great was the trouble from this source that an ordinance was passed by parliament enacting that severe punishment should be dealt upon all who demanded wages above the standard price, and even more severe penalties inflicted upon those who should consent to pay higher wages. It was, however, many years before England recovered from the terrible blow which had been dealt her from the pestilence. While Europe had been ravaged by pestilence the adherents of France and England had continued their struggle in Brittany in spite of the terms of the truce, and this time King Edward was the first open aggressor, granting money and assistance to the free companies, who pillaged and plundered in the name of England. The truce expired at the end of 1348, but was continued for short periods. It was, however, evident that both parties were determined ere long to recommence hostilities. The French collected large forces in Artois and Picardy, and Edward himself proceeded to Sandwich to organize there another army for the invasion of France. Philip determined to strike the first blow, and, before the conclusion of the truce, to regain possession of Calais. This town was commanded by a Lombard officer named Almeric of Pavia. Free communication existed, in consequence of the truce, between Calais and the surrounding country, and Jeffrey de Charny, the Governor of St. Omer, and one of the commissioners especially appointed to maintain the truce, opened communications with the Lombard captain. Deeming that like most mercenaries he would be willing to change sides should his interest to do so be made clear, he offered him a large sum of money to deliver the castle to the French. The Lombard at once agreed to the project. Jeffrey de Charny arranged to be within a certain distance of the town on the night of the 1st of January, bringing with him sufficient forces to master all opposition if the way was once opened to the interior of the town. It was further agreed that the money was to be paid over by a small party of French who were to be sent forward for the purpose of examining the castle, in order to insure the main body against treachery. As a hostage for the security of the detachment, the son of the governor was to remain in the hands of the French without, until the safe return of the scouting party. Several weeks elapsed between the conclusion of the agreement and the date fixed for its execution, and in the mean time the Lombard, either from remorse or from a fear of the consequences which might arise from a detection of the plot before its execution, or from the subsequent vengeance of the English king, disclosed the whole transaction to Edward.
