O'Flaherty V. C by George Bernard Shaw — Read

Preface:

It may surprise some people to learn that in 1915 this little play was a recruiting poster in disguise. The British officer seldom likes Irish soldiers; but he always tries to have a certain proportion of them in his battalion, because, partly from a want of common sense which leads them to value their lives less than Englishmen do (lives are really less worth living in a poor country), and partly because even the most cowardly Irishman feels obliged to outdo an Englishman in bravery if possible, and at least to set a perilous pace for him, Irish soldiers give impetus to those military operations which require for their spirited execution more devilment than prudence.
