Although I am An Old Man, I must confess that I was not present on the night of Mr. Revere's ride, and cannot state with any certanty exactly what he said. The Phrase "the British are coming" is generally attributed to a fellow by the name of Longfellow, you may have heard about him. If not, you can read some about this historic ride made famous in Longfellow's famous poem "Paul Revere's Ride" (1863) HERE.
Who was writing poetry, not historical documentation. That's merely one thing he got wrong, as your link states, the poem is "generally inaccurate".
Revere would not have said "The British are Comming", or the "English", because they considered themselves to be Englishmen, and were, on April 19, 1775, trying to assert their rights as Englishmen. They were not (yet and with some exceptions, notably Sam Adams and perhaps Ben Franklin) trying to separate themselves from the Mother Country.
