Harry threaded his way amongst these, some way up a ravine, which wound to the right. The firing now seemed quite close; indeed, he could see smoke floating up to the dear sky. But surely El Obeid could not be there, in the middle of a mountain pass, commanded on all sides by higher ground! The army must surely have been attacked on the march. He turned a corner, from which the valley ran for some distance straight, and came suddenly on volumes of smoke, pierced by incessant flashes of fire, not a thousand yards in his front, while every now and then a spent bullet came pattering against the rock behind which he crouched, trying to make out whether those nearest him were friends or foes. Firing was also going on from the higher ground to right and left, and one or two of these points were visible from Harry's present position. He had no field-glass, but he carried a small pocket telescope of great power, and adjusting this, and holding it steadily with some difficulty against the rock side, for the field of vision was very small, and his hand shook with excitement, he made out that the men holding these were certainly Arabs. And presently some wounded men of those engaged in the valley to his front falling to the rear, and coming within five hundred yards of him, and clear of the smoke, he perceived that they were Arabs too. And then the fearful truth broke upon him. The spent bullets which fell towards him came from his friends. The army had been enticed into the defile, round which the Mahdi's troops were posted. When it was hopelessly entangled, a body of Arabs, which had lain in ambush for the purpose, had closed in upon their rear to cut off retreat, and these were the men now in front of him. Though he felt convinced that this must be the state of the case, Harry did not give up all hope that the Egyptians might fight their way through, though with severe loss, to the other end of the defile, and to ascertain this he went back, and then began mounting the higher ground, trying to work round to the front of the position. This he had to do very cautiously, to avoid falling in with groups of Arabs, whom he was perpetually sighting. Indeed, to get near the edge of the rocks commanding the defile without being observed was impossible, but by making a wide detour he kept clear of them. And thus, after the lapse of some hours, and with occasional difficult climbing, he reached a lofty point, from which he could distinguish the sides of the ravine held by the Arabs and the pall of smoke which covered the doomed square, fighting like a lion at bay, surrounded by the hunters. For eagerly as he searched with his telescope in every direction he could perceive no line of advance or retreat; every point appeared to be barred by the enemy. There seemed to him only one hope; if General Hicks could hold on till nightfall, perhaps he might push through backwards or forwards under cover of the darkness.
