Last time we spoke about the battle for Kohima and the mop up of the Admiralty islands. The battle for Kohima led to battles raging over the Kohima Ridge. At one point only 2500 allied defenders were facing nearly 15,000 Japanese. Numerous features fell to the Japanese top Kohima ridge. The Japanese were taking heavy casualties while pushing the defenders close to Kohima. A decisive moment presented itself, the Japanese had an open shot against Dimapur. However, mostly because of animosity towards General Mutaguchi the chance to deliver a kill blow was lost. If Dimapur had been taken, it may have changed the entire Burma War. Over in the Admiralty Islands, Los Negros and Manus were finally all mopped up and now the allies had forward airfields to further smash the inner Japanese perimeter. General MacArthurs triumphant return to the Philippines was on its way.

Last we spoke, General Mutaguchi had initiated a grand offensive against Kohima. General Slim, knew the seizure of Kohima would be attempted only in conjunction with the seizure of the much more important target, Dimapur. It was at Dimapur where an enormous allied supply dump lied over the Ledo-Imphal line, it was the hub for which all allied activity in the region revolved. If Dimapur fell, the province of Manipur would be impossible to defend and the Brahmaputra valley would be interdicted thus cutting off all overland supply to China. To everyone's shock the Japanese instead invested an entire division to attack Kohima. Slim thought this was a enormous blunder on the part of General Sato Kotoku, going as far as to ask the RAF not to bomb the Generals HQ as “it never struck him that he could inflict terrible damage on us without taking Kohima at all”. In truth it was not really Sato at fault, it was more so upon his superior General Kawabe Mazakazu who did not trust nor like Mutaguchi and rightly suspected the man’s megalomaniac plan to invade India.
Thus Mutaguchi’s Operation U-Go, the intended invasion of India saw the 33rd and 15th divisions closing in on Imphal by the end of March as the 31st Division attacked Kohima. General Cowan’s 17th Division was able to effectively retreat to Imphal by April 4th, with the 49th Brigade acting as rearguard. Meanwhile General Yanagida had just replenished ammunition and provisions after the battle at Tonzang and now ordered the 214th and 215th Regiments to resume their advance. Colonel Sasahara Masahiko’s 215th regiment departed Singgel on March 27th and crossed the India-Burma border by April 3rd. They advanced to Churachandpur by the 7th as the 214th followed closely behind them.
Meanwhile, the Right Assault Unit, the Yamamoto unit had been in hot pursuit of General Gracey’s 20th division since the start of April, and the 3rd battalion, 213th regiment of the Mitsui Unit had just captured the town Chamol. Additionally the 1st battalion, 60th regiment attempted, but failed to break through Laiching Hill in late March. Afterwords the unit was ordered to turn back and attempt a development of Gravey’s left flank by Moving through Lamlong and then Kampang in early April. To the north, General Yamauchi’s Divisional Head
