That siege of Colchester is the most romantic incident that has survived in the history of the town. It is the story of a last desperate attempt of the Royalists to contend with the Parliamentary forces that had everywhere overwhelmed the King's supporters after a bitter warfare of over six years. It was a gallant attempt, and the more so because Essex was not a county favourable to the King's cause. Sir Charles Lucas, at the head of this enterprise, was a younger member of the Lucas family, seated at Colchester. In the beginning of June 1648, a Royalist rising under Colonel Goring had been checked at Blackheath by the Parliamentary general, Fairfax. A portion of Goring's force crossed the Thames into Essex, and lay at Brentwood. This was an opportunity which Essex sympathisers could not let slip. Lucas and his friends, gathering a body of adherents, galloped down the road to Chelmsford, where the Committee of Parliament was in session, and seized them, afterwards continuing their progress to Brentwood, where they effected a junction with Goring's band. Their forces thus united, a counter-march was made upon Chelmsford again, and continued to Colchester; Lord Capel, Sir George Lisle, and many others joining on the way. On June 12, Goring, in command of this body of four thousand Royalists, approached Colchester, and found the Head Gate closed against him by the unsympathetic citizens, but a slight skirmish soon enabled him to force an entrance. He had not intended to remain at Colchester, but the swift pursuit that Fairfax organised from London gave the Royalists no time to continue their projected march into the Midlands. The day after Goring had entered Colchester, Fairfax had assembled his forces on Lexden Heath, and immediately sent a trumpeter to demand surrender. The inevitable refusal was the signal for a battle outside the town, on the London Road; a contest which resulted in the retirement of the Royalists within the walls. The Head Gate still existed, its bolts and bars in perfect order, but as the Royalists fell back through it into the town, two hundred or more of the Parliamentary troops dashed through in pursuit. Their ardour cost them their lives, for Lord Capel at the head of a determined band pushed back the gate upon the bulk of the enemy, thrusting his walking-stick through the staples as the door closed. The eager advance-guard, thus cooped up within the walls, were all slain.
