Another fire minutes, and the sentry and trench were passed. Skirting by the great fortress, they bore up for the British trenches, crossing as they did so several rows of ditches and earthworks. Then they lay down and listened. Close at hand there was a hum of voices, while away on the left a sharp musketry fire was being maintained, the flicker of the exploding powder cutting the darkness at every second. In front all was pitch blackness in the valley in which they stood, but higher up on the elopes beyond fires were burning, and dark figures were occasionally silhouetted against them as they passed. "Now for it!" whispered Phil. "If there is any firing lie on your faces. We don't want to be killed by our own side." Sneaking through the mud and mire on hands and knees the three crept forward in absolute silence. Soon the last trench was passed, and the British earthworks loomed in the distance. At last they were close to liberty and friends. Not more than sixty yards separated them, and already the murmur of the men's voices could be heard, when, with a sharp exclamation, Phil disappeared. There was a scuffle, a startled cry of astonishment and fear, and the loud report of a musket. "Quick, help me!" Phil cried from the rifle-pit into which he had fallen. Then there was a choked cry, and all was silence for a few moments. With a growl of rage Tony threw himself into the pit, almost smashing Phil as he fell. "That you, Tony?" the latter asked coolly. "Yes, it's me sure enough, mate. Are yer hurt, old man?" "Not a bit, but it was a hard struggle. I fancy the Russian is dead, for I gave him a tremendous blow on the head with my iron bar. Now, let us push on, for the alarm has been given, and it will mean capture if we stay." But the Russian sharpshooters had taken the alarm. Occupying a row of pits, each of which was sufficiently large to hold one man, they had orders to worry the besiegers by their fire, and to be always on the look-out for an assault. At the report of their comrade's weapon they imagined that they were about to be attacked, and poured volley after volley at the British earthworks. Instantly the sharp crackle of Minie rifles broke out, and Phil and his friends found themselves in the awkward position of receiving fire from their friends. "Down in here for your lives," cried Phil; and within half a minute they were wedged in the pit, while a perfect hail of bullets swept overhead. Both sides imagined that a sortie was taking place, and the alarm spreading, the guns on either side opened fire, and a perfect torrent of shell hummed in the air and burst with deafening crashes in the darkness. A loud scuffling was then heard in the British trenches, there was a sharp order, and a host of dark figures sprang over the earthworks and dashed at the Russians.
