This deliberate attempt to preserve as much of the old life and interests as the war would allow was in part a self-imposed discipline and a refusal to be stampeded; in part it was an effort to make London tolerable for those who were on leave from their service abroad and at home; and in part it was an instinctive struggle to retain something familiar in an unfamiliar world and to refresh the brain with a diversion in which war had no share. The years from 1915 to 1919 saw a prodigious output of new literature and music; and, if it is still too early to judge of its quality, there can be no question about the intellectual stimulus which it supplied. Every kind of book was read and discussed; every new school of painting had its followers; and love of music, ceasing to be the foible of the few, became the craving of the many. Though not yet conspicuously prompt in payment, the gratitude of thousands is due to the devotion of Sir Thomas Beecham and of his supporters for the opera which they maintained at Drury Lane with untiring enterprise and energy; without their labours, Covent Garden would be as dead as the London Opera House; no opera in English would ever get a hearing; and in 1917 and 1918 London would not have had its mixed programme of English, Russian, French, Italian and German opera. II Early in 1918 came the black days of the last German offensive. All the optimism and relief of 1917 evaporated before the quick, merciless rain of blows that battered Amiens and threatened Calais, shattered Rheims and overhung Paris. In the southwesterly onrush of 1914 the French declared that, if Paris fell, they would transfer their seat of government to Bordeaux (as they did) and, if need be, to the foot-hills of the Pyrenees; in 1918 any defeat was temporary, for in time the new American levies must burst by sheer weight of metal through any army that had been carded down by four years of fighting; but by 1918 many were asking themselves whether the French spirit would still be equal to this last desperate resolution, whether the British could carry on with a spear-head through their line at Amiens and whether the Americans would make headway in a country as completely overrun as Belgium had been.
