Beyond this trench the doctors and nurses were forbidden to go, and the officer in command warned the Americans to beware of stray shells.
Under these circumstances they contented themselves by occupying some of the rear hollows, to which the wounded would retreat to secure their services.

Dr.Kelsey and Nanette, the French girl, established themselves in one hollow at the right, while Dr.Gys and Patsy took their position in another hollow further to the left.

There they opened their cases of lint, plaster and bandages, spreading them out upon the sand, and were soon engaged in administering aid to an occasional victim of the battle.
One man who came to Patsy with a slight wound on his shoulder told her that a shell had exploded in a forward hollow and killed outright fifteen of his comrades.

His own escape from death was miraculous and the poor fellow was so unnerved that he cried like a baby.
They directed him to the rear, where he would find the ambulance, and awaited the appearance of more patients.

Gys crawled up the mound of sand in front of them and cautiously raised his head above the ridge.
Next instant he ducked to escape a rain of bullets that scattered the sand about them like a mist.
"That was foolish," said Patsy reprovingly.
