18th. Sir Charles Lucas sent an answer about exchange of prisoners, accepting the conditions offered, but the Parliament’s general returned that he would not treat with Sir Charles, for that he (Sir Charles) being his prisoner upon his parole of honour, and having appeared in arms contrary to the rules of war, had forfeited his honour and faith, and was not capable of command or trust in martial affairs. To this Sir Charles sent back an answer, and his excuse for his breach of his parole, but it was not accepted, nor would the Lord Fairfax enter upon any treaty with him.

Upon this second message Sir William Masham and the Parliament Committee and other gentlemen, who were prisoners in the town, sent a message in writing under their hands to the Lord Fairfax, entreating him to enter into a treaty for peace; but the Lord Fairfax returned, he could take no notice of their request, as supposing it forced from them under restraint; but that if the Lord Goring desired peace, he might write to the Parliament, and he would cause his messenger to have a safe conduct to carry his letter. There was a paper sent enclosed in this paper, signed Capel, Norwich, Charles Lucas, but to that the general would return no answer, because it was signed by Sir Charles for the reasons above.

All this while the Lord Goring, finding the enemy strengthening themselves, gave order for fortifying the town, and drawing lines in several places to secure the entrance, as particularly without the east bridge, and without the north gate and bridge, and to plant more cannon upon the works; to which end some great guns were brought in from some ships at Wivenhoe.

The same day, our men sallied out in three places, and attacked the besiegers, first at their port, called Essex, then at their new works, on the south of the town; a third party sallying at the east bridge, brought in some booty from the Suffolk troops, having killed several of their stragglers on the Harwich road. They also took a lieutenant of horse prisoner, and brought him into the town.

19th. This day we had the unwelcome news that our friends at Linton were defeated by the enemy, and Major Muschamp, a loyal gentleman, killed.

The same night, our men gave the enemy alarm at their new Essex fort, and thereby drew them out as if they would fight, till they brought them within reach of the cannon of St. Mary’s, and then our men retiring, the great guns let fly among them, and made them run. Our men shouted after them. Several of them were killed on this occasion, one shot having killed three horsemen in our fight.

20th. We now found the enemy, in order to a perfect blockade, resolved to draw a line of circumvallation round the town; having received a train of forty pieces of heavy cannon from the Tower of London.

This day the Parliament sent a messenger to their prisoners to know how they fared, and how they were used; who returned word, that they fared indifferent well, and were very civilly used, but that provisions were scarce, and therefore dear.

This day a party of horse, with 300 foot, sallied out, and marched as far as the fort on the Isle of Mersey, which they made a show of attacking, to keep in the garrison. Meanwhile the rest took a good number of cattle from the country, which they brought safe into the town, with five waggons laden with corn. This was the last they could bring in that way, the lines being soon finished on that side.

This day the Lord Fairfax sent in a trumpet to the Earl of Norwich and the Lord Goring, offering honourable conditions to them all, allowing all the gentlemen their lives and arms, exemption from plunder, and passes, if they desired to go beyond sea, and all the private men pardon, and leave to go peaceably to their own dwellings. But the Lord Goring and the rest of the gentlemen rejected it, and laughed at them, upon which the Lord Fairfax made proclamation, that his men should give the private soldiers in Colchester free leave to pass through their camp, and go where they pleased without molestation, only leaving their arms, but that the gentlemen should have no quarter. This was a great loss to the Royalists, for now the men foreseeing the great hardships they were like to suffer, began to slip away, and the Lord Goring was obliged to forbid any to desert on pain of present death, and to keep parties of horse continually patrolling to prevent them; notwithstanding which many got away.
