While a fight is in progress, a man has no time to think of anything but the deadly work in hand. It is afterwards, in quiet moments, that he cannot but reflect on the causes of warfare, the root ideas that develop into so terrible a harvest of pain and misery. Burnet, with less than a year's soldiering behind him, had not become hardened. He was not content with knowing that killing was his duty: he felt bound to go a step farther back, and ask himself, was his duty right? Amid much that was puzzling his thoughts all converged to the same conclusion: force could only be overcome by force. The Germans had elected for military force as the efficient agent of civilisation. All that they had done since the war began showed that German civilisation was rotten to the core. It was a system in which lying, low cunning, treachery and brutality were, not tolerated, but applauded. The nations that cherished different ideals, or, to put it on the lowest ground, desired to live their own lives unmolested, had either to submit to material loss, moral degradation, the cowed and hopeless existence of slaves, or to stand up defiantly against this monstrous tyranny and fight it with its own weapons. Only thus could they save their souls. CHAPTER XVII RAISING THE SIEGE Burnet felt that the checks they had suffered were not likely to cause such tenacious fighters as the Turks to abandon their object. The fact that the attacks had been made by Turks and not by Halil's Arabs was clear proof that the enemy's high command attached importance to the capture of the island. With ample resources in their rear it could not be doubted that artillery would be brought up, and then the inevitable end was a matter of a day or two, perhaps only of hours, unless help came. Such help had been promised, but Burnet knew well enough that the strategic plans of the coming campaign could not be disarranged for his benefit, and though the possession of the island was of some importance to the security of the British left flank, it might well be that other considerations would prevent the dispatch of a relief force. In any case relief might not arrive in time. Whether Rejeb would allow his men to prolong their resistance when the odds against them became overwhelming was a question that gave Burnet some concern. He thought it fair to put the situation frankly before the young chief, who was mending but slowly, and was in no condition to take an active part in the defence. Rejeb replied with equal frankness. "The burden is truly heavy upon us, my brother," he said, "but we will not cast it from our backs until there is no more hope. What if we should steal away by night? Without our horses we should fall a prey to Halil's mounted legion. Moreover, even if I escaped alive, my name would be evermore a reproach. Surely it is better to fight and die than to run and live dishonoured."
