“I can’t go with you to Petrograd, girls,” she said quietly enough, however. “Listen, please, so I can make matters plain to you, for you may be ordered to leave at any moment. Barbara, I want you to write my father and mother and try and make them see I had no choice in this decision. But you must not speak of the circumstances to any one else. It would be dangerous for me and for us all if you betray this confidence. The officer who talked with me just then is Colonel Feodorovitch. He is very near General Alexis and tells me that General Alexis has been wounded. The wound is not considered serious and he refuses to give up his command or to leave the fort until the final moment for retreat. Neither must his soldiers learn of what has taken place. His own surgeon is with him now and will remain with him. But there is a chance that they will also require a nurse. Colonel Feodorovitch came to find one before we all got away. By accident he saw me first and requested me to remain behind. I could not refuse.”

“Mildred!” Nona and Barbara exclaimed in unison, with no attempt to conceal their dismay, almost their horror.

“But you can’t accept, Mildred,” Barbara expostulated. “If you do I shall not leave you. Why, what would your mother and father and Dick think of my deserting you at such a time? Besides, don’t you remember that General Alexis himself wanted us safe in Petrograd before the retreat. He would be bitterly opposed to your being chosen to remain behind. Didn’t you speak of this to Colonel Feodorovitch?”

“I couldn’t, Barbara,” Mildred insisted. “It would have been such a long story and Colonel Feodorovitch knows about as much English as I do Russian. It would only have looked as though I were shirking a most important duty. General Alexis will not recall ever having thought or spoken to me, at a time when the Russian army, perhaps the whole Russian nation, is dependent on his failure or success. If I can do even the least thing to help him at such a crisis, why, how could I refuse? Please try and see this as I do, Barbara, you and Nona. There may be nothing for me to do. General Alexis’ wound is not serious or he could not retain his command. I must leave you now; I am wanted at once. I’ll join you in Petrograd as soon as it is humanly possible.”

But Barbara had clutched Mildred’s coat.

“You shall not stay alone. I am almost your sister and I won’t allow it.”

Quietly Mildred unclasped the younger girl’s hand.

“For my own sake I would give a great deal to have you stay, Bab, but we have no choice. Remember, we are under discipline like soldiers. We must do as we are commanded.”

With this Mildred returned inside the fortress.

At the same instant Nona Davis and Barbara Meade heard their names being called. At once they moved forward and were assisted inside the wagon, which soon after passed out of the gate and moved creakingly along the main road in the direction of the Styr River.
