The war continued meanwhile to be irregular and spontaneous. Great noblemen or plain gentlemen, confederations of towns and counties raised at their expense small corps, asked for a commission from king or Parliament, and warred against each other with ardor, but without violence and without cruelty, as men of a common origin, often of the same family, who did not wish to break off all amicable relations forever. Blood flowed and the country already suffered, but the bitterness of the antagonistic passions had not yet taken possession of the combatants. In the eastern, central, and southeastern counties, the most thickly peopled and the richest, the Parliamentarians were in the ascendant. The preponderance pertained to the king in the north, in the west, and in the south-west. London was surrounded by counties devoted to Parliament, which formed, as it were, a formidable girdle for it. At Oxford, the king found himself placed in an advanced post.

In the month of February (1643) the queen arrived, animated and confident. She had succeeded in interesting in the king's favor the States of Holland. The Stadtholder, her son-in-law, had helped her with all his resources. She brought four ships loaded with supplies and troops. Admiral Batten did not contrive in time to intercept the convoy which landed at Burlington. The town was immediately cannonaded. The queen saw the balls fall even in her apartment. She fled into the country and sheltered herself under a bank. Lord Newcastle went to seek her with a body of troops, to conduct her to York. She installed herself there, and a mass of Catholics soon hastened to enroll themselves under her flag. Henrietta-Maria made no haste to rejoin her husband; she liked to reign alone and to maintain with her caressing ardor the zeal of her partisans. Hamilton and Montrose came from Scotland to confer with her upon the means of attaching that kingdom to the cause of the king. Hamilton wished to win over Parliament. Montrose was desirous of making use of a corps of Irishmen under the orders of the Earl of Antrim, to subjugate and massacre the Presbyterian chiefs, rouse the highlanders, and take possession of the whole of Scotland. Intrigues with the Parliamentary commanders were carried on as much as conferences with the Royalists. Sir Hugh Cholmondeley promised to surrender Scarborough. Sir John Hotham appeared disposed to open the gates of Hull to the queen. Parliament began to grow uneasy.

The friends of peace took advantage of this moment to propose fresh negotiations. "It has been said in this House," said Sir Benjamin Rudyard, "that we were bound in conscience to finish the shedding of innocent blood; but who shall answer for all the innocent blood which is about to flow if we do not march to peace by the means of a prompt treaty?" His motion, which involved nothing less than the disbandment of the two armies as a preliminary of the negotiations, was rejected; but it was agreed to send to Oxford five commissioners entrusted to discuss, for twenty days at first, a suspension of arms, then a treaty. The committee, at the head of which was the Earl of Northumberland, set out from London on the 20th of March.

The king received the commissioners well, and their relations with the court were polite and courteous. The Royalists were magnificently treated at the residence of the Earl of Northumberland, who had caused his household to follow him; but when the negotiations were begun ill-feeling reappeared in full force. Neither the king nor Parliament had abated any of the conditions resolutely rejected before the war. One evening the emissaries of Parliament believed they had gained something; on the morrow morning, the written reply of Charles did not resemble his words of the previous day; his councillors and the emissaries of the queen had induced him to alter his resolve. Secret and personal intrigues did not succeed better than official negotiations. The king had promised his wife never to make peace without her approbation, and she angrily wrote to him to dissuade him from it. These manœuvres corresponded with the secret wishes of the king, who did not desire peace. He ended by offering to the negotiators to return to the Houses, if the latter were willing to transport the seat of Parliament at least twenty miles from London. Upon this message the Houses suddenly recalled their commissioners, and, by an order so pressing that they deemed themselves compelled to set out on the same day (April 15th), although it was late, and their travelling coaches were not ready.

On the same day the Earl of Essex took the field again. Hampden would have preferred that a hasty march should be made to Oxford, there to besiege the king. The earl refused this, even when he had taken Reading, an indispensable town for the safety of Parliament. Complaints were uttered concerning his delay and hesitation. The most violent among the leaders of the Commons spoke even of appointing a successor. Hampden, Fairfax, Lord Manchester, Sir William Waller, had obtained successes and rendered great services. Colonel Cromwell, already famous for his bold strokes, as fortunate as they were skillful, had done more still. He was lamenting one day with Hampden the inferiority of the Parliamentary cavalry, constantly defeated in the little engagements which had taken place with the cavaliers. "What would you?" said Cromwell; "your troops are most of them old, decayed serving-men and tapsters. Do you think that the spirits of such base and mean fellows will be ever able to encounter gentlemen that have honor and courage and resolution in them? I will raise men who have the fear of God before them, and I warrant you they will not be beaten." The levies of volunteers which he had formed, fanatical, proud, and severe of manner, engaged in the war for conscience sake, and under the orders of Cromwell from confidence in him. They already composed, at the opening of the campaign of 1643, a body of a thousand men, the germ and nucleus of the famous "Ironsides."

The bitter speeches against Essex came to no result. Complaints were made, but there was a disinclination to separate from him. The ill-will of the leaders, however, was manifested by the destitution in which the army was left, through the insufficiency of the resources and the irregularity of its pay. A royalist plot, upon the point of bursting forth in the city, was discovered: two of the conspirators only, Challoner and Tompkins, rich citizens of London, suffered the extreme penalty. Edmund Waller, a member of the House of Commons and already a famous poet, repurchased his life with cowardly revelations. Many important men were compromised, and while Parliament perceived that conspiracy was going on at its doors against its safety, successive disasters overtook its arms and placed its cause in peril.

A great loss—that of Hampden—was the signal for these reverses. A trifling encounter of cavalry had taken place on the 18th of June, in the plain of Chalgrave, a few leagues from Oxford. Prince Rupert defeated the Parliamentarians. Hampden was there. "I saw him," said a prisoner, "go away, contrary to his custom, from the field of battle before the end of the action. His head was bent low, his hands rested upon the neck of his horse; without doubt he is wounded." The people of Oxford were agitated, almost fearing to rejoice. The king sent one of his physicians, a country neighbor of Hampden, to know whether he did not want assistance. A thought of conciliation towards this powerful adversary had crossed the mind of Charles. Doctor Giles found Hampden dying: a bullet had shattered his shoulder. He was told, however, who had sent to enquire after him, and with what intention. A violent agitation seized the wounded man. He wished to speak, but death had already frozen his tongue; he expired a few instants afterwards. When he was no longer to be feared, the people rejoiced in Oxford; while in London, and in nearly all the kingdom, the grief was as violent as it was profound.

"Never had man inspired so much confidence in a people. Whoever belonged to the national party, no matter in what degree or for what motives, counted upon Hampden for the success of his wishes. The more moderate believed in his wisdom, the more passionate in his patriotic devotion, the more honest in his uprightness, the more intriguing in his skill. Prudent and reserved, while ready to brave all perils, he who had never yet been wanting suddenly disappointed all hopes. A marvellous good fortune, which forever placed his name in the high position assigned to it by the expectation of his contemporaries, and perhaps saved his virtue as well as his glory, from the rocks whereon revolutions impel and shatter their noblest favorites!"
