What if Dupont doesn't corner the market?The U.S. War Department discovers that it has less than a year’s supply of saltpeter, a main ingredient of gunpowder. All commercial quantities of saltpeter are imported from India through Britain. After a secret meeting in Washington, Lammot du Pont, grandson of the founder, is sent on a mission to London to corner the market ostensibly for his own company, but in fact, for the government. He secures enough of the raw material to provide for U.S. needs for the rest of the war.
