The tradition that Col Arthur Wellesley, later to be the Duke of Wellington, leading a British detachment from Vandiperiyar to Bodinayakanur, then over the High Range and into the Coimbatore plains to cut off Tippu Sultan's retreat from Travancore, was the first Englishman in the High Range appears to be belied by the dates involved. If the story is a dozen years too early for Wellesley, it is quite possible that some other officer in General Meadow's Army may have had that distinction. Unfortunately, no record of that pioneering mountain crossing has been traced. What is available is a record of the surveying of this terrain in 1816-17 by Lt Benjamin Swayne Ward, son of Col Francis Swayne Ward to whom we owe many of the early views of Madras and South India Now available in lithprints.
Ward and his assistant Lt Eyre Connor were on orders to map the unexplored country between Cochin and Madurai and so they followed the Periyar into the mountains and then headed north into what at that time was described as "the dark impenetrable forests of the High Range". They lost men to at least one elephant charge, suffered agony from leech bites and once ran so short of food that a deer run down and being feasted on by wild dogs was manna for the party and their jungle guides. The subsequent report by Ward and Connor was to lead to the Periyar Dam project, completed only in the 1890s,but for the present they were more pre occupied getting into the mountains that they could see towering in the distance from Bodi. Then, on 14 October 1817, "the weather having improved the ascent into the High Range began".
