About ten days after the Anzio landing on 22 January 1940, the invasion force received orders to move forward. The Guards Brigade attacked and captured the group of agricultural buildings known as the Factory, suffering heavy casualties.

The Factory was to be the start line of the attack, at 15.10 hours on 31 January 1944. The plan was for 2/Foresters to move through the Guards Brigade with men from the King's Shropshire Light Infantry and the Duke of Wellington's Regiment.

They were to move forward and stop just short of the railway lines at Campoleone and the Foresters to pass through, cross the railway and seize Campoleone station.

The KSLI and Dukes came under heavy mortar and machine gun fire but reached their objectives with tank support.

The Foresters came under fire at the start line but advanced, passed through KSLI and Dukes, and proceeded to cross the exposed railway line. They immediately came under tank fire from close range and from numerous machine-gun nests. Many Forester officers and men fell. The CO, Lieutenant Colonel GRG Bird, ordered the Foresters to withdraw for about 300 yards while he called for artillery fire to try to soften the resistance.

The Foresters resumed the attack but were hurled back by ferocious concentrations of shell fire, mortar and small arms fire. Although they attacked with grim determination and valour they came to a standstill. The strongest company consisted of only 40 men and the weakest company was down to 20 men. All the company commanders were casualties. The CO, adjutant and mortar officer were all hit. Colonel Bird had to be evacuated, under protest. Command of the Battalion passed to Major Johnnie Hackett.
