“Then they must be still in the neighbourhood!” exclaimed Jack, “and we may be in time to overtake them.”

“Oh no, captain,” answered Herr Groben; “I fear not, for dey mount upon two horses and gallop away.”

“At all events, if you can supply us with a guide to show us the way they have taken, we will pursue them,” said Jack.

“Perhaps one of my pupil vill go, for dere moder, Matame Paskievich, is very unhappy at the thoughts the officers were made prisoner, as she consider that they were under her protection; and as dey come as friends, dey should be allowed to go away as friends.”

As there was no time to be lost, Jack, ordering Green to remain, with a couple of men in each boat, set off, accompanied by Archie and Herr Groben, who promised to find him a trustworthy guide, though he showed no inclination to go himself. The name of Paskiewich had struck Jack, and, on making inquiries from the old tutor, he found that the owner of the house was the commandant of the fort.

“I think, sir,” observed Archie, who was walking by his side, “if that is the case, we shall be able to exchange the colonel for Mr Higson and Tom.”

“I would rather get them back without having to do that,” said Jack; “the colonel is to be liberated on his parole; but, should we find it necessary, we shall be able, as a last resource, to recover them as you propose.”

On arriving at the house they were met by Madame Paskiewich and her two daughters. Jack, fortunately recollecting the colonel’s message, delivered it to his wife, who expressed herself very grateful for the kind treatment he had received, and assured them how grieved she was that, notwithstanding all her precautions, the Cossacks had captured the two officers. Jack, in reply, expressed his conviction that it was from no fault of theirs, and comforted them greatly by telling them that probably in the course of the day the colonel would be enabled to return to them.

On hearing of their want of a guide, Madame Paskiewich at once consented to allow her eldest boy to show them the way the Cossacks had gone, though she believed that by this time they were far beyond pursuit Herr Groben’s pupils soon made their appearance, and the eldest, Ivan, who spoke English very well, without hesitation undertook to guide them, and to make inquiries on the way as to where any troops were stationed, so as to prevent them from being surprised. Jack, though perfectly sensible of the risk he ran, resolved to persevere; and, accompanied by young Ivan, at once set off at the head of his party, who, as they were well armed, had no fear of the result should they meet three times their number.

They had gone some distance, when Jack learned, from Ivan’s inquiries, that the Cossacks were already a long way ahead; he at length began to despair of recovering his first lieutenant or Tom; he felt, too, the imprudence of advancing farther into the enemy’s country, when, before he could secure his retreat, the foe might gather between him and the boats. He was at last obliged unwillingly to confess that he must give up the pursuit.
