He served in an ambulance unit during World War I, was wounded in action in France and returned to the UK in 1917.
[1] Most of Barringer's written works were originally published in the 1920s and 1930s, and included the three volumes of the Neustrian Cycle and three independent historical novels set in medieval England.
Barringer's main body of work, the Neustrian Cycle, is a trilogy beginning with Gerfalcon; these novels were set around the fourteenth century in an alternate medieval France called Neustria (historically an early division of the Frankish kingdom).
According to John Clute, "The basic premise, vaguely presented, is that the Merovingian Dynasty does not split apart c. AD 750; instead, Neustria survives, and at the time of the three tales (c. 1400) is still thriving."
He notes further that "The sequence's alternative-world displacement serves not as an opening for magic but as a freeing of LB's imagination; the Neustria Cycle is far more intense and eloquent than his more-straightforward historical novels.
