That night Jansen escaped from his undignified captivity, and having first made the round of the Russian guns and spiked them all, quietly shook the dust from off his feet, turned his back upon the Russian lines, and went over to the enemy, being admitted into Azof by its Mussulman holders with joy and thanksgiving.

On the following morning, when the order was given to train the guns upon the city walls and to open fire, the treachery of Jansen was discovered. The Bombardier Peter Alexeyevitch, when this information was brought to him, was a terrible object to behold. Great spasms of passion shook him from head to foot, while his face—black as any storm-cloud—worked in contortions and grimaces like the features of one in a terrible fit. For a few moments he said no word. Then he took his note-book and wrote therein large and prominent the name Jansen. After which he gave orders for the assault of Azof, guns or no guns, and in a few moments the brave Preobrajensk were in full career towards the walls of the city.

The guns opened fire upon them so soon as the guard became conscious of the surprisingly rash intentions of the Russians; but the shot flew over their heads. Boris, mindful of the Tsar's words to him while still in Moscow, that he should do his best to be the first man into Azof, led his company cheering and waving his sword. Russians have never held back when there was storming work to do, and the troops advanced quickly at the double, singing, as Russians love to do, one of their stirring military songs.

The musketry fire opened from the top of the walls as they came to close quarters, and though the shooting was very wild, still many wide gaps were made in the ranks. In a moment the foot of the wall was reached, and now came the difficult work of ascending. Scaling-ladders were placed, and knocked ever from above, and placed again. Scores of men endeavoured to climb the wall without the aid of ladders, but were easily shot down or knocked on the head if they ever succeeded in climbing within reach of the sharp swords and scimitars waving in readiness above.

The din was deafening, the cries of Christian and Mussulman outvying the roar of musketry. Now and again a squad of Russians firing from below would clear the wall, and a ladder would be placed for half-a-dozen brave fellows to rush upwards and be cut down by new defenders who came to fill the gaps of the fallen. Once a roar of applause was set up by the Russian hosts as a Russian officer, followed by half-a-dozen men, rushed up one of the ladders, and with a shout of triumph stood upon the top of the wall, waving their swords, and shouting to their companions to follow. This triumph was short-lived. First one man fell, pierced through the heart by a bullet; then another and another was knocked on the head, while those who essayed to come to their rescue were shot down in their attempt to mount the ladder. At length there remained alive the officer alone, he who had first surmounted the wall. This officer was Boris, whose superior agility had once more stood him in good stead, and enabled him to climb where the rest had failed. That same activity appeared, however, to have got him into a terrible fix. Alone he stood for a few moments, fighting bravely but hopelessly against a dozen swords, until at length, to the consternation of his friends below, he was seen to receive a blow which tumbled him off the wall upon the Azof side, and no more was seen of him.

For an hour or more the Russians fought bravely on, endeavouring to obtain a foothold upon those grim walls, but all in vain. The Tartar women brought boiling water and threw it down upon the "Christian dogs," together with every sort of filth, and large stones. Every inhabitant of the city appeared to have come out upon the walls in order to assist in beating off the infidel; and though many fell pierced by Russian bullets, they were entirely successful in their patriotic endeavours, for, with the exception of the half-dozen men who followed Boris upon the walls, no single Russian succeeded in mounting the ladders, or in any other way effecting a footing within the Mussulman stronghold.

Meanwhile the guns of the town, probably aimed by the treacherous though much provoked Jansen, rained fire and hail upon the main body of the besiegers, who, with spiked guns, were unable to retaliate. Peter the Bombardier was gloomy and black. He strode among his guns, superintending the efforts of his smiths to get them into working order; he swore at his generals right and left, in a manner ill-befitting a humble bombardier; he swore with yet more deadly wrath at Jansen, and with greater justice. But in spite of all his ferocity and fury he did not lose his discretion; and finding that his troops were doing and could do no good under present circumstances, the Tsar gave orders that the assaulting columns should retire. Thus the day, the first of many, passed without result.

As time went on, and Peter found that his attacks upon Azof made no progress, but that he lost daily large numbers of his best soldiers to no purpose, he decided reluctantly that until he should become possessed of a fleet which could blockade the city by sea, while he attacked it at the same time, and in force, by land, he must abandon all hope of capturing the place. At present, as he had now realized to his loss, the city could be reinforced and revictualled at any moment. Besides this, his mainstay in the science of artillery attack, Jansen, had basely failed him; he had no one competent to take his place. Such an officer, together with clever engineers, must be invited to enter his service as quickly as might be—an Englishman, a Frenchman, even a German again, but not a touchy and quarrelsome and treacherous one, such as Yakooshka had proved himself.
