It has been frequently supposed, and doubtless seems to have been a prevailing opinion at the time, that if the king, instead of sitting down before Glocester at the end of August, had marched upon London, combining his operations with Newcastle's powerful army, he would have brought the war to a triumphant conclusion.[248] In these matters men judge principally by the event. Whether it would have been prudent in Newcastle to have left behind him the strong garrison of Hull under Fairfax, and an unbroken though inferior force, commanded by Lord Willoughby and Cromwell in Lincolnshire, I must leave to military critics; suspecting however that he would have found it difficult to draw away the Yorkshire gentry and yeomanry, forming the strength of his army, from their unprotected homes. Yet the parliamentary forces were certainly, at no period of the war, so deficient in numbers, discipline, and confidence; and it may well be thought that the king's want of permanent resources, with his knowledge of the timidity and disunion which prevailed in the capital, rendered the boldest and most forward game his true policy.
_Efforts by the moderate party for peace._--It was natural that the moderate party in parliament should acquire strength by the untoward fortune of its arms. Their aim, as well as that of the constitutional royalists, was a speedy pacification; neither party so much considering what terms might be most advantageous to their own side, as which way the nation might be freed from an incalculably protracted calamity. On the king's advance to Colnbrook in November 1642, the two houses made an overture for negotiation, on which he expressed his readiness to enter. But, during the parley, some of his troops advanced to Brentford, and a sharp action took place in that town. The parliament affected to consider this such a mark of perfidy and blood-thirstiness as justified them in breaking off the treaty; a step to which they were doubtless more inclined by the king's retreat, and their discovery that his army was less formidable than they had apprehended. It is very probable, or rather certain, even from Clarendon's account, that many about the king, if not himself, were sufficiently indisposed to negotiate; yet, as no cessation of arms had been agreed upon, or even proposed, he cannot be said to have waived the unquestionable right of every belligerent, to obtain all possible advantage by arms, in order to treat for peace in a more favourable position. But, as mankind are seldom reasonable in admitting such maxims against themselves, he seems to have injured his reputation by this affair of Brentford.
