On 30 May, the brigade set off; the plan was to advance 160 miles to the town using the Pinhmi road as an axis. Their first priority was for the need for an area for a small landing strip for evacuating the sick and wounded as well as an area for supplies to be dropped. Calvert had hoped to reach and even capture Mogaung by 5 June.
Lakum The march was difficult – thick jungle intersected by deep ravines and the occasional sporadic firefight with the Japanese. Nevertheless, on 2 June the South Staffordshires and the Gurkhas captured the village of
Lakum after a fierce encounter with the Japanese. The village was a low laying hill overlooking the plain two miles south west of Mogaung. On the following day, another series of bitter encounters forced the Japanese off the surrounding hills – the Gurkhas seized a hamlet, later dubbed 'Gurkha Village', after wiping out the forty strong garrison there. They captured intact a large
ammunition dump, fifteen lorries and a camouflaged hospital full of medical supplies, as well as many sick Japanese soldiers. Many of these tried to escape without success and many more committed suicide. Calvert had his headquarters operational just south of Lakum and a small airstrip was hastily laid from which supplies were arranged to be flown in and dropped by
C-47's. The wounded and sick could be flown out by using
Sentinel aircraft and even the new
Sikorsky R-4 helicopters. An RAF liaison officers set up a position from which to use air support from the US
1st Air Commando Group for further combat sorties in taking Mogaung. Calvert also built up a store of medical, food and military supplies before any major attack went in. At the same time local
Kachin groups led by former
Burma Rifles officers who had established control of the area joined Calvert's men to provide vital intelligence on Japanese movements. The following day two platoons of the Lancashire Fusiliers captured a vital point on the Mogaung river known as the Tapaw Ferry that would prove useful if the Chindits needed an escape route. The villages of Mahaung, Natgyigon and the Pinhmi bridge on the outskirts of Mogaung were key positions in its defence; once these had fallen the Japanese hold on the town would become untenable. In Mogaung itself the courthouse and railway station were potential areas for heavy resistance as they were the two main all brick buildings. Over the next few days the brigade got supplied – they were delivered
PIAT anti tank weapons as well as
flamethrowers,
3 inch and
4.2 inch mortars with thousands of rounds as the only means of heavy fire support. Japanese artillery was causing casualties but Calvert was eventually able to call in
P-51 Mustangs of 1st Air Commando in an attempt to silence the Japanese positions.
Pinhmi bridge and outskirts The attack on the Pinhmi to Mogaung road where the vital Pinhmi bridge crossed the Wetthauk Chaung river began on 7 June. As they advanced closer to Mogaung the Staffordshires found and destroyed a Japanese ammunition dump and the Lancashire Fusiliers later captured the village of Pinhmi. An attempt on the bridge the following day however failed as the Lancashires were repelled from concealed Japanese positions which ranged along a fifteen foot high embankment incurring heavy casualties. They then launched a number of counterattacks but were driven off. On 10 June the Gurkhas attempted to take the bridge again; the first attempt ended in failure but the second in a wide flanking move succeeded in taking the bridge. Among them was Captain
Michael Allmand's heroic feat in ensuring the capture of the bridge. The attacks cost nearly 130 casualties but Calvert's brigade was securely established along the axis of the Pinhmi-Mogaung road. The
monsoon then broke later that day and conditions were tough for the men of the 77th Brigade;
malaria,
trench foot and
typhus were soon rife. Calvert learnt that two more Japanese battalions arrived to reinforce Mogaung essentially replacing casualties, and seeing the difficulty he then sent a messenger to Stilwell to alert him to the situation; but was not received with any sympathy. Stilwell eventually sent the 1/114th Chinese Infantry Regiment from the 38th Division to support the Chindits. Calvert assessed the situation on June 12; many battalions were reduced to a company which meant the brigade total consisted of no more than 750 fit men. Calvert was concerned with the number of wounded and the sick having to endure the poor conditions –
slit trenches were impossible due to the wet conditions; men would have to lay face down in the mud if they were under shell fire. Many of the wounded however were determined to stay and fight rather than be flown out. Over the next few days conditions began to improve many of the wounded were flown out and supplies were brought in once more. On June 15 Calvert continued his attacks, fighting to secure a ridge closer to the town. The Court House was taken the next day, and the area extending to the Mogaung River and up to the outskirts of Natgyigon was cleared. At the cost of some fifty casualties (some from friendly fire) they succeeded and drove around a hundred Japanese out of the village in addition to killing some seventy of them. Whilst consolidating their position in the village a Japanese patrol was ambushed and taken out; they had not realised the village had been in British hands.
Mogaung who won the VC during the Battle of Mogaung Calvert planned his next attack for 23 June towards Natyigon, a key position and the last outer bastion of Mogaung. At first light on that day the final assault was launched; every available fit man was called up; cooks, orderlies and even Headquarters personnel. The Chinese attacked towards the railway station along the railway embankment which was effectively a last line of defence. Despite a heavy bombardment the attack failed and the Chinese were held back with intense Japanese machine gun fire. The Chindits had no choice but to halt along this line for the remainder of the day. One of the men involved was Rifleman
Tulbahadur Pun; his single-handed gallantry as part of the Gurkhas attack on the 'Red House' earned him a nomination for the Victoria Cross. The other nomination fell to Captain
Michael Allmand who attacked a machine-gun position holding up his remaining company. He knocked out the position with grenades but was mortally wounded in the process. The Chinese provided some fire support but did not take part in this attack, instead protecting the flanks and cutting off any Japanese escape attempt. The assault by the Gurkhas totally unbalanced the Japanese and Takeda had no other choice but to withdraw or risk his battalions being destroyed. The final attack was on the railway station on 25 June – the Chinese attack from the South was postponed but the Lancashires and the South Staffordshires went in anyway and after more heavy fighting finally took the battered remains and met up with the Chinese. With the British having a major foothold in the town, the Japanese launched a number of counterattacks that night, but they were beaten off. The following morning Chindit and Chinese patrols found Japanese positions outside the town abandoned. With the battle largely over the Chindits consolidated their position in Mogaung, but they were physically and mentally exhausted. The brigade at the end of the battle had fewer than 550 men left of fighting strength. The Lancashire Fusiliers, King's Regiment and South Staffordshires could only muster 300 between them and the 3/6th Gurkhas had 230 left fit. ==Aftermath==
