Historical references to London's sounds

‘The drums beating every where as if an enemy were upon them’

He tells me also, how, upon occasion of some 'prentices being put in the pillory to-day for beating of their masters, or some such like thing, in Cheapside, a company of 'prentices came and rescued them, and pulled down the pillory; and they being set up again, did the like again. So that the Lord Mayor and Major Generall Browne was fain to come and stay there, to keep the peace; and drums, all up and down the city, was beat to raise the trained bands, for to quiett the towne, [. . .] and in Cheapside, both coming and going, it was full of apprentices, who have been here all this day, and have done violence, I think, to the master of the boys that were put in the pillory yesterday. But, Lord! to see how the train-bands are raised upon this: the drums beating every where as if an enemy were upon them; so much is this city subject to be put into a disarray upon very small occasions.
