"A" Company climbed a third of the way up a spur before coming under heavy machine gun fire and light mortar fire and was pinned down. Calling for artillery and mortar support from 16th Field Regiment, Royal New Zealand Artillery and the United States Army, "B" Company 2nd Chemical Mortar Battalion, the fire support provided could not dislodge the entrenched machine gun and rifle pits.

"D" Company which was climbing a spur parallel to the right of "A" Company and also found the going difficult. At 15:00, D Company finally crossed the ridgeline. Snowstorms began in the afternoon and hampered the evacuation of the wounded and "A" Company was able to advance. "B" Company then joined the two forward companies to consolidate the position. 3 RAR lost 12 killed and 24 wounded, while the 2nd Chemical Mortar Battalion suffered two wounded. At 06:30 on 8 March, "B" Company secured the rest of Hill 410 without opposition after the enemy withdrew during the night.
