His recipe was concentrated artillery-fire, attack by aircraft with bombs and cannon, and, above all, engagement at close range with hand-grenades and with a new close-combat weapon which has to this day kept its German Army nickname —the Molotov Cocktail. This weapon, still a great favorite in domestic revolutions, has an interesting history.

I thought this weapon was first used by the Finns during the Winter War of 1939-40.

You may be right although I've seen references to its first use in Spain by the Nationalist, by the Japanese in the battle of Khalkhin Gol and as you stated, in Finland.
