The Allies missed a number of lost opportunities to end the Battle of Sevastopol early on during the fighting (for instance, they managed to set off one of the Russian powder magazines, which destroyed one of the major redoubts in the Russian defensive line, but didn't end up pressing their advantage). Presuming that the Allies capitalize on an incident like the one mentioned and are able to seize the city and its defenses without months and months of tedious investment and high casualty siege/trench warfare, would the shock of the decisive defeat bring the Russians to the negotiating table any quicker than IOTL?
