QUOTE : The battle for the Wall tended to ebb and flow like the tide, Haung noted. The attackers would crest the Wall and fight like demons for every stone of territory in an effort to establish a safe zone from which to expand their presence. The battle would descend from carefully ordered lines into pockets of a chaos. Each soldier forgot, in those moments, that they were fighting for their country, that they were weapons of their respective generals. In those moments, as swords stabbed and swung, as shields were raised and men screamed out in fear and anger, they were totally selfish, they were fighting only for their lives. That is not to say that there not moments of altruism, but even those had overtones of selfishness, of self-preservation. You saved the man next to you, if you could, so that they in turn could save you. Once the Mongols were pushed from the Wall, the tide ebbed and a moment of calm descended. Each man, Haung included, spent their first breath wondering whether they were still alive and unhurt. The second breath was given in thanks that all was well. With the third intake of life giving air, thoughts turned to their comrades. The selfishness and joy of survival was brushed away, hidden in the pit of shame that each man dug for themselves in their first real battle. In that small window between high and low tide, civilisation returned.
