However, by the end of the 18th century non-sparkling pinkish wine production still accounted for over 90% of the Champagne region's production. The French Revolution and following Napoleonic wars temporarily derailed the popularity surge for Champagne. To save some of their noble clients from the guillotine, Champagnes merchants altered business records by replacing the titles of their clients with "Citizen". As many nobles fled to other countries, the merchants did their best to make sure cases of their favorite Champagne followed. During the Napoleonic wars, Europeans ports were subject to an endless stream of blockading and counter-blockading. Sales agents like Louis Bohne of Veuve Clicquot devised creative schemes to smuggle their wines to their clients. The agents even tried to turn both victory and defeat into sales opportunities. During Napoleon's invasion of Russia, Charles-Henri Heidsieck traveled by horseback ahead of the French Imperial Army on their way to Moscow. Armed with cases of Champagne, Heidsieck was prepared to do business with whoever was the victor. After the defeat of Napoleon, the Champagne region itself was occupied by Russian forces. During the occupation, Champagne was used as requisition and tribute. As her cellar was being emptied of her wine, the Widow Cliquot is reported to have said "Today they drink. Tomorrow they will pay". Her words would be prophetic because for the next century, until the Russian Revolution of 1917, the Russian empire would be the second largest consumer of Champagne in the world.
