If the Londoners fairly claimed some credit for the part they had taken towards the relief of Gloucester, still more credit was due to them for the bold stand they made a fortnight later (20 Sept.), at Newbury, against repeated charges of Rupert’s far-famed cavalry. Again and again did Rupert’s horse dash down upon the serried pikes of the London trained bands, but never once did it succeed in breaking their ranks, whilst many a royalist saddle was emptied by the city’s musketeers, whose training in the Artillery Garden and Finsbury Fields now served them in good stead. Whilst the enemy’s cannon was committing fearful havoc in the ranks of the Londoners they still stood their ground "like so many stakes," and drew admiration even from their enemies for their display of courage. "They behaved themselves to wonder," writes the royalist historian of the civil war, and "were, in truth, the preservation of that army that day."(621) Notwithstanding, however, all their efforts, the day was undecided. Neither party could claim a victory. Essex was glad enough to make his way to Reading, whilst Charles retired to Oxford. On their return to London (28 Sept.) the trained bands received an enthusiastic welcome, the mayor and aldermen going out to meet them at Temple Bar.
Ten days later the services of the trained bands were again required to assist in regaining the town of Reading, which had been occupied by the royalists as soon as Essex had quitted it. Six regiments were to be despatched for the purpose. Two regiments of the city’s trained bands were chosen by lot, as before, and the remainder of the force was made up out of the auxiliaries and the trained bands of Southwark and Westminster.(622) Orders were issued that if any member of the appointed regiments failed to appear on parade, his shop should be closed, and he himself expelled beyond the line of fortifications.(623)
In no long time a mutinous spirit broke out among the trained bands, who, in the midst of an attack on Basing House, the mansion of the Marquis of Winchester, in the following month insisted upon returning home, and the siege had to be abandoned. On the 28th November the sheriffs of London, accompanied by a deputation of aldermen, appeared at the bar of the Commons and boldly desired that the city regiments with Essex might be called home. Alderman Fowke or Foulke, a leading spirit in the city and staunch parliamentarian, was one of the sheriffs at the time, and acted as spokesman. He laid before the House a plain statement as to how matters stood. The fact was that the troops were unpaid, and that no money was forthcoming. If money was found for the trained bands the civic authorities, in consideration of the critical times, promised to do their best to persuade them to remain longer in the field. The House resolved to raise £5,000 for the city’s forces on this understanding.(624) A month later (30 Dec.) the Common Council formally approved of a request made by both Houses of Parliament that two or three regiments of the trained bands should be sent to reinforce Waller, who was endeavouring to recapture Arundel.(625)
