From Burma '44: The Battle That Turned World War II in the East, by James Holland (Grove Atlantic, 2024), Kindle pp. 10-12:
Before taking over 7th Indian Division, Messervy had been Director of Armoured Fighting Vehicles in New Delhi and had been a vociferous advocate of more tanks in theatre. It had taken much beating of drums, but eventually he had managed to prove to his superiors that medium tanks such as US-built Lees and Shermans could operate in South-East Asia. The 25th Dragoons had been the first to equip with these 30-ton machines, and it had been planned some days earlier that during the night of 4/5 February the regiment would cross over the Ngakyedauk Pass and report for duty with 7th Division to the east of the Mayu Range, ready to take part in Messervy’s planned assault on Buthidaung.
Later that night, C Squadron also crossed the pass. Among them was twenty-year-old Trooper Norman Bowdler from Dunchurch in the English Midlands. Just a week before, Bowdler had been the loader in his five-man crew, but when the driver had got sick he had taken over and now was responsible for getting their mighty Lee up and over this treacherous pass – and in the dark. He found it a terrifying experience. Above them, Allied aircraft were flying over in order to disguise the sound of the tanks, which would have easily carried to the Japanese positions in the still night air. ‘It was a bit dodgy,’ Bowdler admitted. ‘I mean, getting a thirty-ton tank round these S-bends – well, some of the bends were so severe that you had to go backwards and forwards, backwards and forwards to negotiate them.’ He was keenly aware that for all the feat of engineering the creation of the pass undoubtedly was, it was little more than a widened mule track and certainly a long way from being a proper road. In some places, parts of it were bridged by laid tree trunks and Bowdler was worried that at any moment stretches of it would simply crumble away and they would tumble down one of the sheer precipices to the ravine floor 200 feet below. ‘It was so narrow,’ he said, ‘and the tank so heavy – we were fully loaded with ammo, fuel and everything.’ At times, one of the tank’s tracks was actually overhanging the edge of the road as he slewed the beast around a corner. At best there was little more than a yard or so either side of the Lee, and the margins were especially tight around corners that offered very, very little room for manoeuvre.
As a result, it took them much of the night to cross. Bowdler found it more difficult going down the reverse side without the natural braking effect of the climb. Low gears helped, but he was very mindful that this huge weight, crunching over a road that would not pass muster in most people’s book, and being hurried by gravitational pull, could all too easily slip out of his control. The levels of concentration needed were immense, but at long last the road began to level out and in bright moonlight they emerged into an area of paddy, criss-crossed with bunds – the paddy walls – and then eventually leaguered up in an area of elephant grass. Not so very far to the south, Bowdler could hear small arms firing and even the occasional shout. He’d already been in battle before, but here, in the milky darkness of the 7th Division Administrative Area, there was a distinct air of menace.
