One difference between the History account and the story that Longfellow tells, is that in the poem, Paul Revere rode by himself while in reality he rode with two friends: William Dawes and Samuel Prescott. A second difference between both stories is the date at which the events take place, in the Longfellow's story the events occurred in april 18th, while they actually happened in april 16th.
