On August 30, 1918, during the Battle of the Scarpe, Pegahmagabow was involved in fighting off a German attack at Orix Trench near Upton Wood. His company was almost out of ammunition and in danger of being surrounded. Pegahmagabow braved heavy machine gun and rifle fire by going into no man's land and brought back enough ammunition to enable his post to carry on and assist in repulsing heavy enemy counter-attacks. For these efforts he received a second Bar to his Military Medal, becoming one of only 39 Canadians to receive this honour.
