The Siege of Saint Petersburg had come to a sudden and violent conclusion. One that onlookers from abroad were not expecting in the slightest. First and foremost, it was assumed that the city would fall, and with it all of Ingria soon after.
If this had occurred, the Bolsheviks would have stolen a vital port from the Russians and would have been able to receive military aid from foreign interest groups which supported them. But in a rather shocking display of firepower. The 6,000 man strong Iron Brigade almost single-handedly obliterated the enemy with an absurd degree of machine guns.
It was still an era where machine guns were not adopted by any military other than the major powers. And even then, they were almost always deployed incorrectly, as if they were another artillery piece.
