Report by the Prime Minister [1] from Paris [at 9 tonight] [2]
indicates that the position most grave.

German break through Mezieres Sedan greatly extended and while has
been effected with armoured divisions with air support, supporting
troops and supplies being rapidly brought up. Time still available
for counter-measures before this support arrives but evidence
points to Gamelin [3] being unequal to the task confronting him
and may be superseded. The Prime Minister by his personality and
force has had a tremendous effect in Paris and has greatly altered
the position. On his urgent representations the War Cabinet here
has agreed to send large fighter and bomber reinforcements to
France for next two or three days to endeavour to obtain local air
superiority while the French re-establish the position.

In my view seriousness of the position cannot be exaggerated.
