How were the angry people armed?

From the text:

Who gave them out, whence they last came, where they began, through what agency they crookedly quivered and jerked, scores at a time, over the heads of the crowd, like a kind of lightning, no eye in the throng could have told; but, muskets were being distributed—so were cartridges, powder, and ball, bars of iron and wood, knives, axes, pikes, every weapon that distracted ingenuity could discover or devise. People who could lay hold of nothing else, set themselves with bleeding hands to force stones and bricks out of their places in walls.
