The rage of Sultan Solyman at the complete defeat of his army and the return of his unsuccessful general was terrible. He immediately resolved to gather another army and flotilla, with which to conquer Malta, to lead this expedition himself, and to take with him a hundred thousand soldiers to insure victory. Preparations were accordingly begun in the great arsenal of Constantinople by collecting arms and ammunition for the carrying out of this purpose, especially including the storage of large quantities of gunpowder. When this had progressed for a few months, La Vallette was informed of the object by his well-paid spies in the Turkish capital. The Knights could not withstand another siege. Their ranks had been so thinned as to leave only a skeleton organization, and the outlook for them was indeed desperate. The Grand Master knew that he could no longer hope to oppose force to force successfully, and that other and effective means must be promptly adopted to cripple and discourage the persistent enemy. La Vallette secretly instructed his unscrupulous spies to fire the arsenal of Constantinople, promising a grand premium if success followed the attempt. This was done. Large stores of powder had already been gathered here for the expedition; and its explosion destroyed not only the arsenal itself, with its store of arms and equipments, but also wrecked the entire fleet, which was being equipped close at hand. The instant destruction of human life, as well as of war materials, was enormous, so great, in fact, that the expedition was necessarily abandoned for the time being. The death of the Sultan of Turkey soon followed the blowing up of the arsenal, thus preventing any renewal of the design against the order.
