ANNEX A. NOTE ON 60% EVACUATION. MINUTE FROM SIR HUGH ELLES TO SIR JOHN ANDERSON. Minister. The 60% Evacuation scheme depends, as you know, for its success upon proper timing. If it is started too early, we cause great hardship and loss to the evacuees. If it is started too late it will fail in a greater or less degree. To complete it satisfactorily we want three full days' notice. 2. The Evacuation would be I assume on Cabinet decision on the advice of the Chiefs of Staff. 3. It is of importance that the Chiefs of Staff should be fully seized of their responsibility in the matter more especially in regard to the bad effects that would result from a premature exodus.
