He emphasised that the great invasion scare (which we only ceased to deride six weeks ago) is serving a most useful purpose: it is well on the way to providing us with the finest offensive army we have ever possessed and it is keeping every man and woman tuned to a high pitch of readiness. He does not wish the scare to abate therefore, and although personally he doubts whether invasion is a serious menace he intends to give that impression, and to talk about long and dangerous vigils, etc., when he broadcasts on Sunday.
