 and offensive to destroy Japanese Forces North of Irrawaddy River was planned with a surprise crossing of the River. 7th Indian Infantry Division and other formations were to seize a bridgehead on Irrawaddy at Pakokku by 15 Feb 45 and move southeast with mechanised forces. Operations of 7 Division initiated by 114 Indian Infantry Brigade was led by 4/5 Royal Gurkha Rifles (Frontier Force). The battalion left Merema on 4 December 1944, and reached the area on 3 February 1945 and close to given objective Pakokku on 5 February 1945, after C Company (Major Beytagh) cleared the road. The Japanese shelled the troops from their positions in Kahnla, a village on the South Bank of the Irrawaddy.

s (LMG's) and twenty rifles were recovered. One of the Battalion’s wounded was CHM Bhagta Bahadur Gurung, whose outstanding courage and leadership in this attack brought him a well-earned Indian Order of Merit (IOM). Major I M Brown MC was awarded one more Bar to MC (Military Cross). These were two of the 41 major awards won by the Battalion during operations in Burma Theatre during World War II.

Further reconnaissance on the 6th of February indicated remainder objective strongly held and on 7 February 4/1 Gurkha Rifles established firm base for the Battalion. On 8 February, the Company led by Major Brown cleared another Japanese position, killing twelve and wounding three Japanese. The main attack planned for early morning hours of 10 February, was pressed without any aerial support due to bad weather. The attack began with one Company and tanks from the 255th Indian Tank Brigade

 (Gordon Highlanders). By the afternoon, three troop companies with armoured support captured their objective. Unfortunately, the Commanding Officer of the battalion was killed in action during the assault. Resistance by Japanese position defended by a battalion was fanatical. One Prisoner of War (POW) was taken and 51 bodies counted. During night 10 February 1945, Japanese launched six unsuccessful counterattacks and on the night of 11 and 12 February 1945, they tried to infiltrate into the Battalion position, without success. On the night of 13 February, troops of the 4/5 Royal Gurkha Rifles first occupied positions closer to Pakokku Village, called Sinlan, then proceeded to search and occupy Pakokku itself. With this operation, unique as it was, decimating nearly battalion strength of Japanese, the first stage of 7 Indian Infantry Division task was completed and foothold gained on the West Bank of Irrawaddy River, for further operations. The operation was magnificent stroke of bravery and deception, making possible the next phase of offensive for the destruction of Japanese in Burma.

Irrawaddy River operations

After the 7th Indian Infantry Division had captured Pakokku, on 14 February, the Allied forces crossed the Irrawaddy River at Nyaung U, North of ancient Burmese capital of Pagan. 7th Division's crossing was made on a wide front. Both the main attack at Nyaung U and a secondary crossing at Pagan (the former capital, and the site of many Buddhist temples) were initially disastrous. Pagan and Nyaungu were defended by two battalions of the Indian National Army

's 4th Guerrilla Regiment, with one held in reserve. The 7th Indian division suffered heavy losses as their assault boats broke down under machine-gun fire which swept the river. Eventually, support from tanks of the Gordon Highlanders firing across the river and massed artillery forced the defenders at Nyaungu to surrender. At Pagan, the defending troops, the INA's 9th battalion, took a heavy toll offering resistance to the (1/11th Sikh Regiment

.
By 20 February, most of the forces crossed the river and captured Meiktila, as planned. Capture Pakokku by 4/5 Royal Gurkha Rifles (Frontier Force) opened way for further operations of 17th Indian Infantry Division. On 19 February, the 4/5 Royal Gurkha Rifles cleared an island, five miles long and three miles broad, in the Irrawaddy River, off Pakokku, which was interfering with forward movement.

On 24 February, the Gurkhas moved south of Pakokku, crossed Irrawaddy River and took over part of Nyaung U bridgehead. On 25 February, a squadron of the 116th Regiment RAC (Gordon Highlanders),part of the 255th Indian Tank Brigade

 supported the assault of the battalion and the village was soon secured, in which seven Japanese including an officer were killed. Throughout the month of April, the allies continued to engage the Japanese in the area and this led to the capture of Letse and Seikpyu. On the morning of the 24th of April, leading troops were pinned down with heavy fire from a ridge with a prominent Golden Pagoda and a monastery. The objective was captured by a company of the 4/5 Royal Gurkha Rifles, under Captain G W Maycock, supported by heavy artillery concentration. Thirty-nine Japanese bodies were recovered. By 30 April Battalion secured Pwinbu and then moved to clear Japanese position at Pagan village. From 5th to 8 May concerted assaults on Japanese positions were launched which a ring around the position from the South on 6th, roadblock in the rear of the Japanese on 7th and assault launched on Pagan Village on 8th.

 had been fought out. The Japanese had been decisively and finally beaten. The Japanese Army in Burma except for those still East of Sittang River had ceased to exist as an organised and integrated force. On 2 May 1945 Rangoon had been reoccupied and General Slim's plans had been brought to a triumphant conclusion. The monsoon was about to break and the next phase was to be a large scale mopping up operations. On 14 May the Battalion left Pagan for what it hoped would be a fairly permanent monsoon location. After several changes of location, the Battalion arrived at Allanmyo, forty mile North of Prome. Orders were soon received on 27 May to move to Prome for further operational tasks.
