For a moment Monk had entertained the idea of marching against Lambert; but he judged his presence in London more necessary. He sent for Colonel Ingoldsby, and informing him what troops would be available, "Be at Northampton three days hence," he said, "and pursue Lambert till you overtake him." Ingoldsby obeyed. On the 22d of April (Easter Sunday) he found himself face to face with the enemy. A little watercourse separated the two armies. There was a parley. Lambert proposed to restore Richard Cromwell. "It is you who overthrew him, and now you would raise him again," said Ingoldsby. "My orders are not to discuss, but to fight you." One of Lambert's squadrons approached the enemy's line. Ingoldsby advanced alone to meet it, conversing in a friendly way with the soldiers. "Now to end the business," said Ingoldsby; and he marched forward, giving the order to his troops not to fire till they were close to the enemy. Lambert's cavalry dropped their pistols without firing. Ingoldsby urged on his horse towards the general. "You are my prisoner," he cried. Lambert put spurs to his horse. Ingoldsby pursued him: he was well mounted, and overtook the fugitive. Lambert surrendered, irretrievably beaten and still more humiliated. On the 24th of April he returned to the Tower.

It was the last expiring effort of the Republic; the elections gave the death-blow. A few of the old leaders, respected or influential in their counties or their boroughs—Ludlow, Scott, Robinson, Hutchinson—alone succeeded in getting re-elected, and these with difficulty. Even an express recommendation from Monk did not support at Bridgenorth the candidature of Thurloe. Royalists of every shade, old and new, Presbyterians or Cavaliers, carried the elections in all directions. The Cavaliers were the most numerous, but they were still prudent and unassuming. The Presbyterians chose one of their number, Grimstone, for Speaker of the new House. The peers, a small number of whom had assembled in their House, were presided over by Lord Manchester, a moderate Presbyterian. Scarcely had the two Houses assembled, when they passed a vote of thanks to Monk; the Lords decreed him a statue. The Commons extended their gratitude even to Ingoldsby, who had suppressed the insurrection of Lambert. Nothing less than the influence of Monk was certainly required to determine so royalist a House to forget the regicide in order thus to honor in Ingoldsby the obedience and courage of the soldier.

The royalist reaction burst forth on all sides with violence and disorder. The Cavaliers in certain parts took possession again of the estates that had been taken from them. They even laid hand on some which had never been theirs. The widow of Cromwell, Lady Elizabeth, fled from London, leaving behind her, it was asserted, concealed goods and jewels which she had taken from the royal palaces. Terror spread among the revolutionary party; the Royalists everywhere rushed to enjoy their triumph. The change of masters was signalized by redoubled anarchy throughout the country.

On the 27th of April Sir John Grenville presented himself at the door of the Council of State, requesting leave to speak with the Lord-general. Monk came out from the house; Grenville placed in his hand a packet sealed with the king's arms. Monk seemed surprised. The messenger was desired to enter. The president inquired from whom he had received these letters. "The king, my master," he answered, "gave them to me with his own hand." It was determined that they should be handed to Parliament, that alone had the right to receive them. Some one proposed to place Grenville meanwhile under arrest. "I have not seen Sir John Grenville for some years," said Monk, "but he is my near kinsman, and I will answer for his presenting himself before the House." Grenville retired at liberty.

Three days later, on the 1st of May, he was introduced to the House of Commons, and he handed to the Speaker a letter from the king, dated from Breda, "in the twelfth year of our reign." As soon as Grenville had retired, Grimstone, standing and uncovered, read aloud the king's letter. The House listened also standing and uncovered. In the House of Lords the president rose, and went to meet Grenville, accompanied by forty-one peers who were then present; and the messenger, recalled shortly afterwards into the House, received the thanks of the assembly.

The king's letters, written by Hyde, were elegant and simple. They promised a general amnesty and liberty of conscience, with only such exceptions or limits as Parliament should think well to assign. All questions of delicacy were in like manner referred to Parliament. The king preserved his freedom of action under the pretext of his responsibility. Similar declarations addressed to the city, the army, and the fleet, were received with acclamations. Admiral Montague despatched on the morrow a message to the king. "I rejoice," he said, "that the king has no need of aid from foreign powers. He will find a sufficient stay in the affection and loyalty of his subjects. I covet nothing so much in the world as the honor of presenting myself before your Majesty, which I hope will not long be delayed."

The two Houses on their part lost no time, and the Lords declared on the 3d of May that, in accordance with the fundamental laws of the realm, the supreme power resided and ought to reside in King, Lords, and Commons. The House of Commons immediately adopted the same resolution, and also decided that a gift of £50,000 sterling should be immediately offered to the king; £10,000 and £5,000 were also voted for his brothers. A jewel valued at £500 sterling was voted to Grenville, but the treasury was exhausted. It was necessary to have recourse to the city, which provided at once for pressing needs. When Grenville arrived at Breda, the bearer of £30,000 in bills of exchange and specie, the king, overjoyed at the sight, sent for the Princess of Orange and the Duke of York, desiring that they should see this gold, so long strange to their hands, taken out of the portmanteau of the messenger.
