On the 20th of August, 1672, the city of The Hague was crowded in every street with a mob of people, all armed with knives, muskets, or sticks, and all hurrying towards the Buytenhof.
Within that terrible prison was Cornelius de Witt, brother of John de Witt, the ex-Grand Pensionary of Holland.
These brothers De Witt had long served the United Provinces of the Dutch Republic, and the people had grown tired of the Republic, and wanted William, Prince of Orange, for Stadtholder. John de Witt had signed the Act re-establishing the Stadtholderate, but Cornelius had only signed it under the compulsion of an Orange mob that attacked his house at Dordrecht.
This was the first count against the De Witts--their objection to a Stadtholder. The second count was that the De Witts had always done their best to keep at peace with France. They knew that war with France meant ruin to Holland, but the more violent Orangists still believed that such a war would bring honour to the Dutch.
Hence the popular hatred against the De Witts. A miscreant named Tyckelaer fanned the flame against Cornelius by declaring that he had bribed him to assassinate William, the newly-elected Stadtholder.
Cornelius was arrested, brought to trial, and tortured on the rack, but no confession of guilt could be wrung from the innocent, high-souled man. Then the judges acquitted Tyckelaer, deprived Cornelius of all his offices, and passed sentence of banishment. John de Witt had already resigned the office of Grand Pensionary.
On the 20th of August, Cornelius was to leave his prison for exile, and a fierce Orangist populace, incited to violence by the harangues of Tyckelaer, was rushing to the Buytenhof prepared to do murder, and fearful lest the prisoner should escape alive. "To the gaol! To the gaol!" yelled the mob. But outside the prison was a line of cavalry drawn up under the command of Captain Tilly with orders to guard the Buytenhof, and while the populace stood in hesitation, not daring to attack the soldiers, John de Witt had quietly driven up to the prison, and had been admitted by the gaoler.
The shouts and clamour of the people could be heard within the prison as John de Witt, accompanied by Gryphus the gaoler, made his way to his brother's cell.
