Poor Richard's Almanac was a yearly almanac that Benjamin Franklin began publishing in 1732. In 1737, five years into the life of the almanac, Franklin included three "enigmatical prophecies" in the almanac. He predicted that:
- A great storm would cause all the major cities of North America to be under water;
- A "great number of vessels fully laden will be taken out of the ports… by a Power with which we are not now at war;"
- and that an "army of 30,000 musketers will land… and sorely annoy the inhabitants."
