a special envoy from Charles II, Lord Arlington, met William in Nieuwerbrug and presented a proposal from Charles. In return for William's capitulation to England and France, Charles would make William Sovereign Prince of Holland, instead of stadtholder (a mere civil servant). When William refused, Arlington threatened that William would witness the end of the Republic's existence. William answered famously: "There is one way to avoid this: to die defending it in the last ditch." On 7 July, the inundations were complete and the further advance of the French army was effectively blocked. On 16 July, Zeeland offered the stadtholdership to William. Johan de Witt had been unable to function as Grand Pensionary after being wounded by an attempt on his life on 21 June. On 15 August, William published a letter from Charles, in which the English king stated that he had made war because of the aggression of the De Witt faction. The people thus incited, De Witt and his brother, Cornelis, were brutally murdered by an Orangist civil militia in The Hague on 20 August. Subsequently, William replaced many of the Dutch regents with his followers. Though William's complicity in the lynching has never been proved (and some 19th-century Dutch historians have made an effort to disprove that he was an accessory), he thwarted attempts to prosecute the ringleaders, and even rewarded some, like Hendrik Verhoeff, with money, and others, like Johan van Banchem and Johan Kievit, with high offices. This damaged his reputation in the same fashion as his later actions at Glencoe. William continued to fight against the invaders from England and France, allying himself with Spain and Brandenburg. In November 1672, he took his army to Maastricht to threaten the French supply lines. By 1673, the Dutch situation further improved. Although Louis took Maastricht and William's attack against Charleroi failed, Lieutenant-Admiral Michiel de Ruyter defeated the Anglo-French fleet three times. In August, the Dutch, Spain and Emperor Leopold, supported by other German states, agreed the anti-French Alliance of The Hague, joined by Charles IV of Lorraine in October. In September, the resolute defence by John Maurice of Nassau-Siegen and Hans Willem van Aylva in the north of the Dutch Republic had finally forced the troops of Münster and Cologne to withdraw, while William crossed the Dutch Waterline and recaptured Naarden. In November, a 30,000-strong Dutch-Spanish army, under William's command, marched into the lands of
