An excerpt from the Field Artillery Journal: Road To Dunkirk
by Henri de la Falaise

EDITOR'S NOTE: Henri, Marquis de la Falaise, is a member of a distinguished French family
having a military background, and several of his close maternal relatives are oficers in the British army.
Educated at Sorbonne University in Paris, he enlisted in the French cavalry (in 1915), at the age of 17.
After active service at the front during 1915-18 he was wounded severely,
but later volunteered for the tank corps and saw action at St. Mihiel.
For his war service he was awarded the Croix de Guerre, and received a second citation.
After the war he worked for various motion picture companies in Hollywood,
and made films in Bali and French Indo-China.
During 1939-40 Marquis de la Falaise was a liaison oficer with the British.
For his services in Flanders he was twice decorated, and after Dunkirk he returned to France.
He was sent to a tank regiment in Brittany; this unit was cut off and captured.
Marquis de la Falaise escaped and made his way to the United States, where he is now living.
Some of the names mentioned in "Road to Dunkirk" are real, others fictitious in order to protect individuals,
some of whom are now prisoners in German hands. All events described are, of course, actual history.
