Churchill was an early and steady supporter of a Channel Tunnel, which was first proposed in 1751. For most of his life he joined in lively and almost continuous discussion of “a fixed link with the Continent.” Indeed, during the 1924-1929 Conservative government, Churchill was seen as “the leading political advocate of a tunnel.”
No evidence exists that Churchill wished to commit a million Allied troops. The British contingent he envisioned was small, and made up of volunteers. Above all, Churchill wanted decision, not hesitation, which he abhorred all his life.
