Mr. Swartz was anxiously soliciting for means to build a church for the use of this garrison, when he was summoned to Madras, to the governor, Sir Thomas Rumbold, who promised him a grant for his church; but, at the same time, informed him that he was to be sent on a mission to visit the formidable Hyder Ali in Mysore, in order to judge how far his intentions towards the English were pacific. He was selected for the purpose on account of his perfect knowledge of Hindostanee, the simplicity of his manner of travelling, and his perfect immunity from any of the ordinary influences of interest or ambition; and he undertook it, as he tells the Society for Promoting Christian Knowledge, because he regarded it as conducing to peace, as opening fresh doors to the Gospel, and as a token of gratitude to the Honourable Company for kindness he had received; "but at the same time," he says, "I resolved to keep my hands undefiled from any presents, by which determination the Lord enabled me to abide, so that I have not accepted a single farthing save my travelling expenses."
On the 1st of July, 1779, he set out from Trichinopoly on this journey, taking one of his catechists, named Sattianadem, with him. He travelled in a palanquin, and took six days to reach Caroor, on the Mysore frontier, forty miles off, where he stayed a month with a young Ceylonese Dutchman in Hyder Ali's service, while sending to ask the Nabob's permission to proceed. All this time he and his catechist preached and gave instruction in the streets. It is curious to find him, on his journey, contrasting the excellent state of Hyder Ali's roads and bridges with the careless disorganization of the public works under the Company. An epidemic fever was raging in Seringapatam, and Swartz pitched his tent outside, where he could conveniently visit the many-pillared palace of the sovereign. He was much struck with the close personal supervision that Hyder Ali kept up over his officers, and with the terrible severity of the punishments. Two hundred men were kept armed with whips, and not a day passed without many being scourged, no rank being exempt, the Nabob's two sons and sons-in-law being liable to be whipped like the meanest groom. Swartz was the unwilling spectator of the punishment of the collector of a district who was flogged with whips armed with nails.
A few hundreds of Europeans, English, German, and French, were in Hyder's pay, encamped about the town, and a German captain lent his tent for public worship. No molestation was offered to any instructions that Swartz attempted to give, and he was very courteously entreated by the Prince himself. The conferences with him were generally held in a hall of marble columns, open to a garden adorned with fruit trees, rows of cypresses, and fountains. Hyder Ali sat on rich carpets, covering the floor, and the Padre was placed next to him. He spoke in general terms of his desire to keep the peace, though the British had violated their engagements, referring to an attempt that had newly been made to march troops through his territory without his permission. To Swartz he was gracious in speech, but the letter he entrusted to him was full of threatening for this and other acts which he considered aggressive; and the general impression brought back by the missionary was that a war was to be expected.
Hyder Ali had presented him with a bag of three hundred rupees for travelling expenses, which it would have been a great affront to return. He, however, made it over to the Government at Madras, and when they would not take it, asked leave to use it as the foundation for a collection for an English orphan school at Tanjore. This was granted, and proved a success. Finding that there was an intention of voting a present to him, he begged instead that a salary might be given to Mr. Pohle at Trichinopoly; and, in consequence, both were enabled to maintain catechists and schoolmasters; for of making a home for themselves, these devoted men never thought. Moreover, Swartz obtained bricks and lime for the building of his English church within the fort; and he bought and enlarged a house half a mile from it, for his Malabar Christians to worship in. His own observations of Hyder Ali's warlike intentions led also to his purchasing 12,000 bags of rice as a provision against the scarcity that too surely attends upon Indian warfare.
In the summer of 1780, these apprehensions were realized. Hyder crossed the Ghauts, and passed down into the Carnatic with 100,000 men, directed by a staff of French officers, and plundered up to the very gates of Madras. Everything was in the greatest confusion; the English troops were dispersed in garrisons, and could not easily be brought together; and one small detachment under Colonel Baillie, who were made prisoners at Conjiveram, suffered a frightful captivity. Sir Eyre Coote did, indeed, keep the enemy in check, and defeat him in several battles, but had not at first sufficient numbers or stores effectually to drive him back; and the whole province of Tanjore was horribly wasted. The irrigation of the district had been broken up by the invaders; there was for three years neither seed-time nor harvest, and the miserable peasants crawled into the towns to perish there, often with their sons carried off to form a regiment of youths whom Hyder Ali was bringing up as a sort of Janissaries.
The unhappy creatures lay dying along the sides of the road, and among them moved from one to another that homely figure in the black dimity dress, and his catechists with him, feeding those who could still swallow, and speaking words of comfort to those who could hear. Some of the English sent a monthly subscription, which enabled Swartz to keep up the supply, so that a hundred and twenty a day were fed; but often in the morning he found the dead lying in heaps, and in one of his letters he mentions that his catechists are alive, as though he regarded it as a wonder and a mercy. Indeed he seems to have been a very Joseph to the Rajah, and even to the English garrison. There was absolutely no magazine for provisions, either for the Sepoys or the Rajah's own troops, and twice he was implored, both by Tuljajee and the Company, to purchase supplies and get them brought in, since they were unable to do so, "for a want of good understanding with the natives who still possessed either rice or oxen to transport it." He was enabled to procure the supply, and then there was no place to store it in but his own new English church, so that he was obliged to hold three services on a Sunday in the other: from eight till ten in English, from ten till twelve in Tamul, and from four till five in Portuguese! About a hundred converts were gained during the famine; but he was forced to teach them very slowly, their mental faculties were so weakened by their state of exhaustion. The whole of the towns of Tanjore and Trichinopoly were, he says, filled with living skeletons, there was hardly an able or vigorous man to be found, and in this distress it was necessary to relax the ordinarily wise rule of never giving any assistance to a person under preparation for baptism, since to withhold succour would have been barbarous cruelty.
When the whole country was overrun by the troops of Mysore, the respect paid to the good Padre was such that he travelled from end to end of it without hindrance, even through the midst of the enemy's camp, and on the only occasion when he was detained, the sentinel politely put it that "he was waiting for orders to let him proceed." It was on one of these journeys that a little lad, named Christian David, the son of one of the converts, was attending him one evening, when, halting at a native village, the supper was brought, of rice and curry. The Padre made so long a grace out of the fulness of his heart, that at last the boy broke in with a murmur that the curry would be cold! He never forgot the reproof: "What! shall our gracious God watch over us through the heat and burden of the day, and shall we devour the food which He provides for us at night, with hands which we have never raised in prayer, and lips which have never praised Him?" The missionaries were always safe throughout the war, and, when Cuddalore capitulated to the French and Mysoreans, Mr. Gericke, who was then at the head of the station, concealed some English officers in his house, and likewise, by his representations to the French general, saved the town from being delivered up to be plundered by Hyder's native troops.
