Not quite as dire as September 15, 1940 but still pretty serious:
"What other reserves have we?"
That was Churchill's question to Air Vice Marshal Keith Park on the penultimate day of the Battle of Britain.
On 15 September 1940 the Germans attempted to draw the Royal Air Force
into a battle of annihilation with their largest and most concentrated
daylight attack against London. They sent 620 fighters and 500 bombers
against the R.A.F's 660 fighters.
September 15, 1940 was also the day that Churchill had decided on to
visit the headquarters of Sir Keith Park, commander of Fighter Command's
11 Group which protected southeast England i.e. where the German's were
headed.
At 2:35, Churchill, who had been watching the plotting table where the
waves of bombers coming in since 10:10 were depicted, noticed that all
the red light bulbs that denoted RAF fighter squadrons in action were
lit and asked the famous question, "What other reserves have we?"
Park's reply:
"There are none."
