Dr. Robert Lyman discusses a new book by David Allison that covers one of the many small battles that made up the large Imphal-Kohima campaign:

When Wavell, by then Viceroy of India, visited Imphal after the battle in October, to bestow knighthoods on the four victors — Lieutenant Generals Bill Slim (14 Army), Montagu Stopford (33 Corps), Geoffrey Scoones (4 Corps) and Philip Christison (15 Corps) — he admitted to Slim that he found the battle hard to follow, as it seemed to have been fought in “penny-packets”. In professing his ignorance of Slim’s great triumph, Wavell nevertheless hit the nail on the head. Sangshak was one of those penny-packet fights which cumulatively determined the outcome of Japan’s audacious invasion of India.

Like many battles in insufficiently examined wars, Sangshak has suffered over the years from a paucity of rigorous examination. Louis Allen’s magisterial The Longest War gave it short treatment in 1984, and very little else. Until now. I’m delighted to say that a Hong Kong-based Australian lawyer with a military background — David Allison — has produced a new account of this crucial battle, and it is absolutely outstanding. It can be purchased here. I recommend it very strongly. It’s not long: at 159-pages of text you can make your way through this in a couple of days, but it is diligently researched, well written and judiciously argued. For those who know something of the battle, the big arguments in the past about the state training of the 50 Indian Parachute Brigade, the temporary breakdown of its commander, Hope-Thomson and the supposed loss of the captured Japanese map and orders by HQ 23 Indian Division, are calmly and satisfyingly explained.

The story can be briefly told. The territory to the north-east of Imphal (centring on the Naga village of Ukhrul) had only the lightest of garrisons and no real defences. Until 16 March it was home to 49 Brigade, which was then despatched to the Tiddim Road to deal with the advance in the south of Lieutenant General Yanagida’s 33 Division. The brigade had considered itself to be in a rear area, and, extraordinarily, no dug-in and wired defensive positions had been prepared. It was one of the most serious British planning failures of the campaign. The entire north-eastern portion of Imphal lay effectively undefended. The gap left by the brigade’s departure had been filled in part by the arrival of the first of the two battalions of the newly raised 50 Indian Parachute Brigade (comprising the Gurkha 152 Battalion and the Indian 153 Battalion), whose young and professional commander, 31-year-old Brigadier M.R.J. (“Tim”) Hope-Thomson, had persuaded New Delhi to allow him to complete the training of his brigade in territory close to the enemy. The area north-east of Imphal was regarded as suitable merely for support troops and training. At the start of March, the brigade HQ and one battalion had arrived in Imphal and began the leisurely process of shaking itself out in the safety of the hills north-east of the town. To the brigade was added 4/5 Mahrattas under Lieutenant Colonel Trim, left behind when 49 Brigade was sent down to the Tiddim Road. To Scoones and his HQ, the area to which Hope-Thomson and his men were sent represented the lowest of all combat priorities. Sent into the jungle almost to fend for themselves, it was not expected that they would have to fight, let alone be on the receiving end of an entire Japanese divisional attack. They had little equipment, no barbed wire, and little or no experience or knowledge of the territory. No one considered it worthwhile to keep them briefed on the developing situation. To all intents and purposes, 50 Indian Parachute Brigade was an irrelevant appendage, attached to Major General Ouvry Roberts’ 23 Indian Division for administrative purposes but otherwise left to its own devices.

Before long, information began to reach Imphal that Japanese troops were advancing in force on Ukhrul and Sangshak. Inexplicably, however, this information appeared not to ring any warning bells in HQ IV Corps in Imphal, which was preoccupied with the developing threat in the Tamu area where the main Japanese thrust was confidently predicted. On the night of 16 March, the single battalion of 50 Parachute Brigade took over responsibility for the Ukhrul area from 49 Brigade, which was hastily departing for the Tiddim Road. They had no idea that an entire Japanese division of 20,000 men was crossing the Chindwin in strength opposite Homalin. On 19 March, large columns of Japanese infantry were reported advancing through the hills.

No one had expected them to be where they were. But the first shock came to the Japanese 3/58 battalion (Major Shimanoe), part of Lieutenant General Sato’s 31 Division – troops whose objective was Kohima, and not Imphal – who were bloodily rebuffed by the determined opposition of the young Gurkha soldiers at an unprepared position forward of Sheldon’s Corner. The 170 Gurkha recruits refused to allow the 900 men of 3/58 to roll over them and inflicted 160 casualties on the advancing Japanese. In the swirling confusion of the next 36 hours, Hope Thomson and his staff kept their heads, attempting to concentrate what remained of the dispersed companies of 152 Battalion and 4/5 Mahrattas back to a common position at the village of Sangshak, which dominated the tracks southwest to Imphal.

It was at this now-deserted Naga village that Hope-Thomson, on 21 March, decided to group his brigade for its last stand, his staff desperately attempting to alert HQ 4 Corps in Imphal to the enormity of what was happening to the north-east. The Japanese columns infiltrated quickly around and through the British positions, heading in the direction of Litan. The Japanese now began days of repeated assaults on the position in a battle of intense bravery and sacrifice for both sides. Hope Thomson’s men could only dig shallow trenches, which provided no protection from Japanese artillery.
