Meanwhile the Ghorkas had been alarmed by the letter of Lord Moira. A great council of Bharadars was summoned to Khatmandu, and the question of peace or war was discussed in a military spirit. It was decided that, as the British had been unable to capture the mud fortress of Bhurtpore, which was the work of men's hands, they could not possibly capture the mountain fortresses on the Himalayas, which were the work of the Almighty. Accordingly, the council of Bharadars resolved on war, but they did not declare it in European fashion. A Ghorka army suddenly entered the disputed districts, surrounded the police stations, and murdered many of the constables, and then returned to Khatmandu to await the action of the British government in the way of reprisals. [Sidenote: Ghorkas superior to Mahrattas.] The war against the Ghorkas was more remote and more serious than the wars against the Mahrattas. The Mahrattas fought in the plains, and trusted in their artillery; but when their gunners were shot or bayoneted, as in the battle of Assaye, they seemed to have lost all life and energy, and were broken up into loose bodies of runaways. The Ghorkas, on the other hand were resolute and hardy mountaineers, with a Rajput pride, and military instincts like the ancient Spartans. Their nerves had not been enfeebled by opium, and they exulted in the strength of their mountain fortresses, which they deemed impregnable against all the world. [Sidenote: Difficult invasion of Nipal.] Those who have ascended the Himalayas to Darjeeling or Simla may realise something of the difficulties of an invasion of Nipal. The British army advanced in four divisions by four different routes. They had first to make their way through a belt of marsh and jungle at the foot of the mountains. They had then to climb precipices and shelves which would have daunted the army of Hannibal. Moreover, it was impossible to storm the fortresses without artillery; and dragging up eighteen-pounders in the teeth of snow-storms and mountain blasts, opening up roads by blasting rocks, and battering down obstructions with field guns, were tasks which would have tested the genius of the ablest commanders.
