During four days of heavy fighting O’Meara, a stretcher bearer, repeatedly went out and brought in wounded from No Man’s Land despite intense artillery and machine-gun fire; he was busy during the whole series of operations, especially in the critical barrage and counter-attack period. Four times he carried water and supplies forward under bursting shells and then returned carrying wounded. On one occasion, he volunteered to carry ammunition and bombs to a portion of trench which was receiving heavy shelling.
