After the Treaty of Ryswick, Gyles was delivered to the captain of an English vessel at the mouth of the Saint John and sailed for Boston, where he arrived on 19 June 1698.
Gyles' knowledge of and fluency in the Indian dialects of Acadia made him invaluable to the governing authorities of New England when war broke out again in 1701.
He served as an interpreter under many flags of truce, sailed with Major Benjamin Church in 1704, and fought with Colonel John March at the Siege of Port Royal (1707).
[5] The memoirs are considered a precursor to the frontier romances of James Fenimore Cooper, William Gilmore Simms, and Robert Montgomery Bird.
[6] A play was produced about his life called John Gyles: an Indian Experience by Theatre New Brunswick's Young Company in 1978.
