The two midshipmen had fought side by side, and were among the last to fall back. Dashing at the top of their speed down the street, they took the first turning, and ran for their lives. They heard the cavalry charge along the end in pursuit of the main body of the fugitives, and were congratulating themselves on their escape when a fresh body of cavalry were seen entering the street at the opposite end, while some of those in their rear turned up the street, and took up the pursuit. The position seemed hopeless, but taking another turn, they dashed down a lane at the end of which they could see the open country, too far distant, however, for them to hope to gain it before they were overtaken. END of Chapter XIX CHAPTER XX. IN A LION'S DEN Upon one side of the lane which the fugitives had entered ran a high wall. Upon the other was a very large mansion. Its lower windows were five feet from the ground. As the lads ran they saw an open window. Without a moment's hesitation they placed their hands on the sill, threw themselves into it, and flung down the window. There was a scream as they entered, followed by an exclamation in English. The boys looked round, and saw a young lady who had started back in terror to a corner of the room. "Are you English?" Jack exclaimed in astonishment. "We are English officers escaping from a Russian prison. In heaven's name do not betray us!" As he spoke the Russian cavalry came along the lane at full gallop. "I am English," the young lady said, as she recovered from her astonishment, "I am governess to the younger daughters of the governor. You are now in his palace. But what has taken place? I heard the firing and went to the window to listen." "We have been aiding in the rescue of a Polish leader who was to have been executed this morning," Dick said. "We succeeded in that, but were attacked and cut up afterwards, and had to scatter. I fear that they will suspect we must have entered this place, for they were close behind us, and there was no other escape possible. Can you conceal us? It seems almost like a miracle finding an English lady here." "A great many of the Russian nobility have English tutors or governesses, and although some went back to England at the beginning of the war, the greater number have remained quietly at their work. I fear that the whole palace will be searched if it is suspected that you have taken refuge here. How imprudent of you to have mixed yourselves up in this rebellion!" "We could hardly help ourselves," Jack said, "but it is too late to discuss that now. Will you look out of the window and see if the lane is empty? If so, we had best make off without delay." The young lady went to the window. "No," she replied at once, "there is a soldier on horseback a few yards to the right."
