Here in this strong City of Refuge which enshrines the title-deeds of human progress and is of deep consequence to Christian civilisation; here, girt about by the seas and oceans where the Navy reigns; shielded from above by the prowess and devotion of our airmen-we await undismayed the impending assault. Perhaps it will come tonight. Perhaps it will come next week. Perhaps it will never come. We must show ourselves equally capable of meeting a sudden violent shock or-what is perhaps a harder test-a prolonged vigil. But be the ordeal sharp or long, or both, we shall seek no terms, we shall tolerate no parley; we may show mercy-we shall ask for none.
