"You are safe?" he shouted.
"Yes," her voice replied.
"Now watch the gateway."
A plank came over, but profiting by their earlier experience, they shoved it off before it came to rest. Another, a longer one, and another, both of which found lodgment squarely between the gate posts. Renwick sprang to the loophole; but the volley that followed spattered harmlessly around him.
He was a good shot with a rifle, and aimed deliberately, dropping the first man that put his foot on the hazardous bridge. Gasping with her exertions Marishka pushed the shorter timber over, but the longer one jammed hopelessly against the gate post.
"Hugh," she cried, "we are lost."
But a strange thing happened then. For as the second man approached the bridge and had even put one foot upon it, a shrill call rang out at the other end of the causeway.
"The retreat!" the officer shouted. "To the rear——"
The look of relief upon the face of the brave fellow who was venturing death upon the precarious timber was reflected in Renwick's own heart, for he spared the man who, with a startled glance over his shoulder, presently caught up with the rapidly vanishing Windt. Renwick rushed out and lifting the dangerous timber hurled it down into the gorge.
Then he caught Marishka by the waist and lifted her.
