Scarcely had the Edict of Amboise been signed when a demand was made upon the English queen for the city of Havre, placed in her possession by the Huguenots, as a pledge for the restoration of Calais in accordance with the treaty of Cateau-Cambresis, and as security for the repayment of the large sums she had advanced for the maintenance of the war. But Elizabeth was in no favorable mood for listening to this summons. Instead of being instructed to evacuate Havre, the Earl of Warwick was reinforced by fresh supplies of arms and provisions, and received orders to defend to the last extremity the only spot in France held by the queen. A formal offer made by Conde to secure a renewal of the stipulation by which Calais was to be given up in 1567, and to remunerate Elizabeth for her expenditures in the cause of the French Protestants, was indignantly rejected; and both sides prepared for open war.[265] The struggle was short and decisive. The French were a unit on the question of a permanent occupation of their soil by foreigners. Within the walls of Havre itself a plot was formed by the French population to betray the city into the hands of their countrymen; and Warwick was forced to expel the natives in order to secure the lives of his own troops.[266] But no vigilance of the besieged could insure the safety of a detached position on the borders of so powerful a state as France. Elizabeth was too weak, or too penurious, to afford the recruits that were loudly called for. And now a new and frightful auxiliary to the French made its appearance. A contagious disease set in among the English troops, crowded into a narrow compass and deprived of their usual allowance of fresh meat and wholesome water. The fearful mortality attending it soon revealed the true character of the scourge. Few of those that fell sick recovered. Gathering new strength from day to day, it reigned at length supreme in the fated city. Soon the daily crowd of victims became too great to receive prompt sepulture, and the corpses lying unburied in the streets furnished fresh fuel for the raging pestilence. Seven thousand English troops were reduced in a short time to three thousand, in a few days more to fifteen hundred men.[267] The hand of death was upon the throat of every survivor. At length, too feeble to man their works, despairing of timely succor, unable to sustain at the same moment the assault of their opponents and the fearful visitation of the Almighty, the English consented to surrender; and, on the twenty-eighth of July, a capitulation was signed, in accordance with which, on the next day, Havre, with all its fortifications and the ships of war in its harbor, fell once more into the hands of the French.[268] [Sidenote: How the peace was received.]
