Word came they were going to try to break through Nangpa La, the deep pass interrupting the range. One of the old salt trading passes, the best pass for many li in both directions. Sherpas would guide, Tibetans who had moved south of the pass. On its other side extended a canyon to their capital, tiny Namche Bazaar, now in ruins like everything else. From Namche trails ran directly south to the plains of Bengal. A very good passage across the Himalaya, in fact. Rail could replace trail in a matter of days, and then they could ship the massed armies of China, what was left of them, onto the Gangetic Plain. Rumours swirled, replaced daily by new rumours. Iwa spent all night at the wireless.
It looked to Bai like a change in the bardo itself. Shift to the next room, a tropical hellworld clogged with ancient history. The battle for the pass would therefore be particularly violent, as is any passage between worlds. The artilleries of the two civilizations massed on both sides. Triggered avalanches in the granite escarpments were frequent. Meanwhile explosions on the peak of Chomolungma continued to lower it. The Tibetans fought like pretas as they saw this. Iwa seemed to have reconciled himself to it: 'They have a saying about the mountain coming to Mohammed. But I don't think it matters to the mother goddess.'
Still, it brought home to them yet again how insane their opponents were. Ignorant fanatical disciples of a cruel desert cult, promised eternity in a paradise where sexual orgasm with beautiful houris lasted ten thousand years, no surprise they were so often suicidally brave, happy to die, reckless in frenzied opiated ways that were hard to counter. Indeed they were known to be prodigious benzedrine eaters and opium smokers, pursuing the entire war in a jerky drugged dream state that could include bestial rage. Most of the Chinese would have been happy to join them there, and opium had made its way into the Chinese army, of course, but supplies were short. Iwa had local contacts, however, and as they prepared for the assault on Nangpa La he obtained some from some military policemen. He and Bai smoked it in cigarettes and drank it as a tincture of alcohol, along with cloves and a pill of Travancori medicines said to sharpen sight while dulling the emotions. It worked pretty well.
Eventually there were so many banners and divisions and big guns collected on this high plane of the bardo that Bai became convinced that the rumours were right, and a general assault on Kali or Shiva or Brahma was about to begin. As confirming evidence he noted that many divisions were composed of experienced soldiers, rather than raw boys or peasants or women – divisions with extensive battle experience in the islands or the New World, where the fighting had been particularly intense, and where they claimed to have won. In other words, they were precisely those soldiers most likely to have been killed already. And they looked dead. They smoked cigarettes like dead men. A whole army of the dead, gathered and poised to invade the rich south of the living.
The moon waxed and waned and the bombardment of the invisible foe across the range continued. Fleets of flyers shaped like sickles shot through the pass and never came back. On the eighth day of the fourth month, the date of the conception of the Buddha, the assault began.
The pass itself had been rigged, and when its immediate defenders were all killed or had retreated south, the ridges guarding the pass erupted in massive explosions and poured down onto the broad saddle. Cho Oyo itself lost some of its mass to this explosion. That was the end for several banners securing the pass. Bai watched from below and wondered, when one died in the bardo where did one go? it was only a matter of chance that Bai's squad had not been in the first wave.
The defences as well as the Chinese first wave were buried. After that the pass was theirs, and they could begin the descent of the giant glaciercut canyon south to the Gangetic Plain. They were attacked every step of the way, chiefly by distant bombardment, and with booby traps and enormous mines buried in the trails at crucial points. They defused or set these off as often as they could, suffered the occasional missed ones, rebuilt a road and rail bed as they descended. It was mostly road work at great speed, as the Muslims gave ground and retreated to the plain, and only their most distant aerial bombardment remained, shots fired from around Delhi, erratic and hilarious unless they happened to make a lucky strike.
