how far is it across the english channel at dunkirk?
On a side note, the closest point across the English channel is 20.7 miles and is just south of Dunkirk at Cap Gris Nez, a cape near Calais in the French dÃ©partement of Pas-de-Calais. From there, one can see the White Cliffs of Dover across the English Channel's Strait of Dover. Were mines really a concern for the evacuating vessels? Yes.
