Passage: Meanwhile, on the western side of Leyte, the XXIV Corps received reinforcements on 7 December with the landing of the 77th Infantry Division under Maj. Gen. Andrew D. Bruce south of Ormoc City. The 77th Division's 305th and 307th Infantry Regiments came ashore at 0700 unopposed, supported by a company from the 776th Amphibian Tank Battalion. However, Admiral Arthur D. Struble's naval convoy was subjected to kamikaze air attacks, fifty-five aircraft making sixteen raids. Yet, the arrival of the 77th Division proved decisive. This enabled the 7th Division to resume its march north, and the enemy defenders were quickly squeezed between the two forces.Moving north, the 77th Division faced strong opposition at Camp Downes, a prewar Philippine constabulary post. Supported by the newly arrived 306th Infantry Regiment, plus the 902nd and 305th Field Artillery Battalions, Gen. Bruce's troops pushed through and beyond Camp Downes on 9 Dec., and entered Ormoc City on 10 December.  The 7th and 77th Infantry Divisions linked up the next day.In its final drive, US troops killed some 1,506 enemy and took seven prisoners while sustaining 123 killed, 329 wounded and 13 missing. With Ormoc City captured, the XXIV Corps and X Corps were only 16 mi (26 km) apart. In between at Cogan, the last enemy salient with its defenses anchored on a concrete blockhouse, north of Ormoc, and held by the 12th Independent Infantry Regiment, resisted the Americans for two days. On 14 December, the 305th Infantry closed on the stronghold, aided by heavy artillery barrages and employing flamethrowers and armored bulldozers. Hand-to-hand combat and the inspiring leadership of Medal of Honor awardee Captain Robert B. Nett cleared the enemy from the blockhouse area, while the leading Company, E, of the 2nd Battalion, 305th Infantry moved forward through intense fire and killed several Japanese soldiers.
