These preparations were of little avail. As the royalist army came on Waller fell back, until at Newbury the opposing armies again tried conclusions (27 Oct.). Notwithstanding some success which attended the parliamentary forces, they failed to attain the main object in view, and Charles was able at the close of the day to continue his march to Oxford, which he entered on the 1st November. (M312) In the meantime better news arrived from the north. Newcastle had at last surrendered to the Scots (19 Oct.), and this intelligence gladdened the hearts of the parliamentary soldiers as well as of the citizens of London. The city might now look for a plentiful supply of coal, a commodity which had become so scarce that in July the civic authorities had received permission from parliament to dig for turf and peat, by way of a substitute for coal, wherever they thought fit.(664) Seeing that it was by the aid of the city that a fleet had been maintained off the north coast, that Berwick had been secured for parliament, and that a free passage had thus been kept open for the Scottish army, the civic authorities thought themselves justified in appealing to parliament for repayment of the money formerly advanced by the adventurers.(665) Notwithstanding the surrender of Newcastle the citizens had to pay a high price for coal owing to a heavy impost set upon it by parliament, until, at the earnest request of the municipal authorities, parliament consented to reduce it.(666) (M313) The close of the year (1644) found the trade and commerce of the city in a deplorable condition. Commercial intercourse with the woollen and linen manufacturers of the west of England had been almost entirely cut off, whilst the blockade of the east coast by the royalist navy deprived the city of a great amount of corn, fish, butter, cheese and other provisions. The citizens were greatly opposed to free trade being allowed with those ports and towns which were in the hands of the royalists,(667) but they were still more anxious to have their trade kept open with the west of England, and they petitioned parliament to that end.(668) (M314) Early in the following year (31 Jan., 1645) a conference was opened at Uxbridge to discuss three propositions for peace which parliament had offered to Charles at Oxford in November last. These propositions involved the abolition of Episcopacy, and the placing the entire command of the army and navy, as well as the future conduct of the war with Ireland, in the hands of parliament. From the outset it appeared very unlikely that Charles would bring himself to accept the terms thus offered. After three weeks’ discussion negotiations were broken off and the so-called "Treaty of Uxbridge" fell to the ground. CHAPTER XXIV. (M315) (M316)
