Notwithstanding liberal grants made by parliament for the defence of Calais, that town was still in danger. On the 29th November, 1453, a letter was read before the Common Council of the City, emanating from the Lord Welles and the Lord Ryvers, asking for assistance towards putting Calais into a state of defence. Further consideration of the matter was adjourned until the following 4th December. By the 7th day of the same month the Council had consulted the commons, who had declared that owing to their numerous burdens and expenses they could contribute nothing to that end.(854) This did not prevent a further application being made early in 1454, for contributions towards the defence of Calais if that town were besieged.(855) Again the commons were consulted, and again they pleaded the excessive burdens they were already called upon to bear, and the losses they had sustained by seizure of their ships and merchandise by the Duke of Burgundy, rendering them unable for the present to undertake any further charges unless steps were taken for the recovery of their goods.(856) An answer to this effect was accordingly delivered by the Common Sergeant on behalf of the citizens, who declared themselves willing at the same time to bear their share with the rest of the realm.(857) An appeal made in August of the same year (1454), for the sum of £1,200 for the same purpose, met with similar failure.(858) The plea of poverty was no idle one, if we may judge from the fact that when, in November of this year, an assessment of half a fifteenth was made on the city wards, eleven out of twenty-five wards were in default.(859) Between the years 1431 and 1451 the citizens had advanced large sums of money to the king, of which more than £3,000 remained in the latter year due to the city.(860) (M457) A crisis, in the meanwhile, was fast approaching. The birth of an heir to the throne urged the Duke of York to take prompt action. Although the majority of the nobles were opposed to him, he had on his side the powerful family of the Nevills, having married Cicely Nevill, sister of Richard Nevill, Earl of Salisbury, the head of the family, and father of the still more powerful Earl of Warwick. Towards the end of January (1454) the Duke of York, the Earls of Salisbury and Warwick, and others of the duke’s supporters, entered the city, each followed by a large force of retainers fully armed. With them came also York’s eldest son, the Earl of March, afterwards King Edward IV.(861)
