"There was an undoubted advantage from the point of view of national unity in having a Liberal rather than a Tory Government in power when war was declared. There was a further advantage in having a Government at the head of affairs which had the support of Labour. This secured the adhesion of the great Labour organisations whose action and sympathetic aid was essential to its vigorous prosecution. Had Labour been hostile the War could not have been carried on effectively. Had Labour been lukewarm victory would have been secured with increased and increasing difficulty. The most prominent and influential leaders of trade unionism worked for victory throughout the War. Without their help it could not have been achieved. But beyond and above all these considerations, as a factor in the attainment of national unity, was the circumstance that the War had been declared by a party which by tradition and training regarded war with the deepest aversion, and has more especially since the days of Gladstone, Cobden and Bright, regarded itself as specially charged with the promotion of the cause of peace."
