The mob, at first only about one hundred strong, now amounted to thousands, and were increasing every moment.

They divided themselves so as to ascend with more speed the various narrow lanes which lead up from the Cowgate to the High Street; and still beating to arms as they went, an calling on all true Scotsmen to join them, they now filled the principal street of the city.
The Netherbow Port might be called the Temple Bar of Edinburgh, as, intersecting the High Street at its termination, it divided Edinburgh, properly so called, from the suburb named the Canongate, as Temple Bar separates London from Westminster.

It was of the utmost importance to the rioters to possess themselves of this pass, because there was quartered in the Canongate at that time a regiment of infantry, commanded by Colonel Moyle, which might have occupied the city by advancing through this gate, and would possess the power of totally defeating their purpose.

The leaders therefore hastened to the Netherbow Port, which they secured in the same manner, and with as little trouble, as the other gates, leaving a party to watch it, strong in proportion to the importance of the post.
The next object of these hardy insurgents was at once to disarm the City Guard, and to procure arms for themselves; for scarce any weapons but staves and bludgeons had been yet seen among them.

The Guard-house was a long, low, ugly building (removed in 1787), which to a fanciful imagination might have suggested the idea of a long black snail crawling up the middle of the High Street, and deforming its beautiful esplanade.
This formidable insurrection had been so unexpected, that there were no more than the ordinary sergeant's guard of the city-corps upon duty; even these were without any supply of powder and ball; and sensible enough what had raised the storm, and which way it was rolling, could hardly be supposed very desirous to expose themselves by a valiant defence to the animosity of so numerous and desperate a mob, to whom they were on the present occasion much more than usually obnoxious.
There was a sentinel upon guard, who (that one town-guard soldier might do his duty on that eventful evening) presented his piece, and desired the foremost of the rioters to stand off.
