To the east of the 7th Marines, the 5th Marines in the right MLR sector ordered a company-size patrol, also on the night of 2–3 July. Company A, 1/5 was directed to attack successively three outposts in the vicinity of the village of Samichon along the river bearing the same name and two miles beyond the point where the MLR crossed the river. After the reinforced company had taken the first two objectives, which were unoccupied, it received orders from division to return to the battalion area. Despite the fact the patrol had ventured far beyond the Marine lines, it did not come into contact with any Chinese forces. A 2/5 combat patrol leaving the MLR just after dawn was successful in inflicting casualties on the enemy, taking prisoners, and destroying enemy field fortifications. The patrol made good progress until a Marine inadvertently set off an enemy mine. This mishap gave away the patrol’s location and prompted reprisal by the Chinese. A one-hour fire fight followed. Then the patrol called in smoke and returned under its cover to JAMESTOWN. Marine casualties were 1 killed and 11 wounded. The second 2/5 patrol that same date was a successful ambush completed 10 minutes before midnight. In the brief clash that developed, Marine ambushers killed 6 enemy and wounded 8 more. The Marine force suffered no casualties. The ambush patrol returned 15 minutes after midnight on 4 July. Even at that early hour division artillerymen had already initiated an appropriate ceremony to mark the Fourth. On 2 July, I Corps had directed the massing of fires on 4 July on the most remunerative targets in each division area. All objectives in the corps sector were to be attacked simultaneously at specified times for a one-minute period by employing a firing technique known as time on target (TOT).[142] Normal daily fires were also to be carried out. Designated as Operation FIRECRACKER, the shoot expended 3,202 rounds in the division sector. Light and medium battalions of the 11th Marines, plus its 4.5-inch Rocket Battery destroyed some enemy trenches, bunkers, mortar and artillery positions, and damaged others. The division reported that the special fires on 4 July had also resulted in 44 known CCF casualties, including 21 dead, and 12 more who were estimated to have been injured. [142] In the TOT technique, participating units time their initial volleys to ensure that their shells arrive on the target at the same time. More casualties, however, resulted from the issuing of another I Corps directive, this one dealing with the conduct of raids to seize prisoners, obtain information about the enemy, and to destroy his positions, supplies, and equipment. Back in June, the EUSAK commander had first stressed to his corps commanders the increased importance of combat raids to obtain additional intelligence during this period of stabilized conflict.
