Don't think Cadogan Street's had a mention...
From another source...
"A legend of one of the British regiments has a reference to the Gallowgate. At Fuente d'Honore, in Spain, the 71st Regiment bore the brunt of the fight. When the contest seemed to be going against the British, Colonel Cadogan waved his hat and cried, "Now, my lads, charge them down the Gallowgate," the scene of the conflict resembling that old Glasgow thoroughfare. With a cheer the 71st rushed on and drove the French out at the point of the bayonet.
A monument to the gallant colonel's memory is in the Cathedral."
I'd like to see what the monument looks like. Can't find a pic on tinterweb. Anyone got one?
