On one occasion, Jan de Witt, having been employed at the Chamber of the States to a late hour of the night, was returning home attended by a single servant, according to his custom, when he was attacked by four assassins. He defended himself for a considerable time, till having received some severe wounds he fell, and his assailants decamped, leaving him for dead. One only, James van der Graaf, was arrested; the other three took refuge in the camp, where, though the States of Holland earnestly enjoined the Prince of Orange and the other generals to use diligent means for their discovery, they remained unmolested till the danger was passed. Van der Graaf was tried and condemned to death. The pensionary was strongly solicited by his friends to gratify the people by interceding for the pardon of the criminals; but he resolutely refused to adopt any such mode of gaining popularity. Impunity, he said, would but increase the number and boldness of such miscreants; nor would he attempt to appease the causeless hatred of the people against him by an act which he considered would tend to endanger the life of every member of the Government. The determination, however just, was imprudent. The criminal, an account of whose last moments was published by the minister who attended him, was regarded by the populace as a victim to the vengeance of Jan de Witt, and a martyr to the good of his country. On the same day a similar attempt was made on the life of his brother, Cornelius de Witt, at Dordrecht, by a like number of assassins, who endeavored to force their way into his house, but were prevented by the interference of a detachment of the burgher guard.
