However, a certain friction was engendered that was later evidenced on both sides. The American ambulance was no longer favored on its trips to the front, pointed preference being given the English and French Red Cross Emergency Corps. This resulted in few wounded being taken to the _Arabella_, as the Americans confined their work largely to assisting the injured on the field of battle. The girls were not to be daunted in their determined efforts to aid the unfortunate and every day one of them visited the trenches to assist the two doctors in rendering first aid to the wounded.
