Note 34 — Chapter IV
Reading edition
One of the Irvines was a hatter; the other was a physician. It was probably the latter—Dr. William Irvine—who was in this expedition, for he was then in command of the Second Pennsylvania Regiment. He had been a captain in Canada about two years. Brigadier-General Irvine was made a prisoner at Chestnut Hill, near Philadelphia, in December, 1777.
