Thank you for the article.
Dieppe lies between cliffs that totally command the landings. 
.
To the east, the "beach" at Puys is a 15 yard wide strip of large stones. It stops abruptly at an overhanging cliff.  There is a narrow cleft in the rock.  It was defended by six concrete pill boxes.  That was the objective for the Royal Regiment of Canada. 
.
Many died before they could get out of the landing craft.  In about 15 minutes the unit had suffered 85% killed, wounded, or captured.
.
At Dieppe itself, the tanks couldn't climb the seawall.
There was bitter fighting in the casino.

West of Dieppe, the South Sask. Regiment landed in a swamp.  With no concern for his own safety, their commander got them across the Rive Scie bridge and saved their lives.  Charles Merritt, VC.

All day a chaplain carried wounded off the beach to be evacuated.  As the last boat was leaving, he got back into the water and walked ashore, because the captured and wounded needed his care more.  John Foote, VC.
