Marine aircraft were on station when Marine ground forces resumed their forward movement at 0830 on the morning of 22 April. A CCF prisoner taken that very afternoon confirmed previous POW statements that the 22d was the opening day of the Fifth Phase Offensive. The front was quiet, however, as the three Marine infantry regiments advanced almost at will. A motorized patrol of Division Reconnaissance Company, led by the commanding officer, Major Robert L. Autrey, had the initial contact with the enemy while advancing on the Division left flank. The two platoons, supported by Marine tanks, found their first indications when searching a Korean roadside hut. Although the natives denied having seen any Chinese soldiers. Corporal Paul G. Martin discovered about 50 hidden rice bowls waiting to be washed. Upon being confronted with this evidence, the terrified Koreans admitted that Chinese soldiers had reconnoitred the area just before dawn. Farther up the road, an ammunition dump of hidden mortar shells was discovered. The enemy had also put up several crude propaganda signs with such sentiments as YOUR FOLKS LIKE SEE YOU HOME and HALT! FORWARD MEANS DEATH. The patrol dismounted and proceeded with caution, guided by an OY overhead. Although the “choppers” were the favored aircraft of VMO-6, the OYs also earned the gratitude of the troops on many an occasion such as this. The pilot gave the alarm just before hidden Communists opened fire. Thus the Marines of the patrol were enabled to take cover, and the tanks routed the enemy force with well placed 90mm shells.[160] [160] Sgt Paul G. Martin, USMC (Ret.), ltr of 2 Jul 56. The KMCs met no resistance worth mentioning when they secured the town of Hwachan and the north bank of the Pukhan just west of the reservoir. Only light and scattered opposition awaited the 5th Marines (Colonel Richard M. Hayward) and the 7th Marines (Colonel Herman Nickerson, Jr.) on their way to the occupation of assigned objectives on Line QUANTICO. _CCF Breakthrough Exposes Marine Flank_ For weeks the Communist forces in Korea might have been compared to an antagonist backtracking to get set for taking aim with a shotgun. There could be no doubt, on the strength of daily G-2 reports, about both barrels being loaded. And on the night of 22 April the enemy pulled the trigger. The KMCs, after taking their objectives, reported a concentration of enemy small-arms fire. At 1800 the command of the 1st Marine Division directed a renewal of the advance at 0700, on the morning of the 23d. This order was cancelled at 2224 by a message calling for all Marine units to consolidate and patrol in zone, pending further instructions.[161] [161] CG 1stMarDiv msg to COs 5th, 7th, 11th Mar, 1st KMC, Tk, and EngBns, 2224 22 Apr 51 in Div In&Out #21.
