I--Four facts which must be emphasized:
(1) The enemy's complete mastery in the air.
(2) The skillful and large-scale employment of enemy parachute and airborne troops,
(3) The flexible and well-directed support of the land troops by ships' artillery of strong English naval units ranging from battleship to gunboat.
(4) The rehearsal of the enemy invasion units for their task; most precise knowledge of the coast, of its obstacles and defense establishments, swift building up of superiority in numbers and material on the bridgehead after just a few days.
