- Captain Paul Stevens: How would you like to wake up one morning and find out that the Germans have invaded England.
- Martin Donovan: We shall split up and then meet in London. Remember, each of you is authorised to kill anyone who disobeys orders. Now infiltrate into British units.
- Air Marshal George Taylor: Allow me to insist once again upon my request again for more radar positions. I ask that top priority be given to furnishing us with new stations.
- British Soldier: How are we gonna recognise these Germans?
