SIGNAL CORPS MEN working in the main frame room of headquarters switchboard installation. The beach area at Anzio-Nettuno was on a slightly higher level than the rest of the beachhead area and was honeycombed with tunnels and caves so far underground that they were bombproof. Wherever possible the installations along the shore were put underground.

RADAR SET IN OPERATION. By 24 February 1944 the first sets of this type were in position on the Anzio beachhead. They were brought in to cope with enemy jamming techniques and “window” (small strips of metallic paper dropped from attacking planes) which had reduced the effectiveness of earlier types of radar. During the night of 24 February a flight of twelve bombers approached in close formation, using the “window” method of jamming. Forty-eight 90-mm. guns directed by radar of the improved type caught them at extreme range over enemy territory and brought down five with the first salvo. The remainder of the formation jettisoned their bombs and fled. (Radar SCR 584.)

FIRING ANTIAIRCRAFT GUN at ground targets. The enemy counterattack down the Albano road on 16–20 February 1944 was the most severe and dangerous of the three main attacks the Germans made on the Allies at Anzio beachhead. On the 17th it looked as if the enemy might succeed in driving down the Albano road from the Campoleone area to Anzio and thus split the beachhead forces. To aid the hard-pressed infantry, all the artillery in the area was brought to bear on the enemy. In addition to 432 guns representing corps and divisional artillery and three companies of tanks, four batteries of 90-mm. antiaircraft guns were employed against ground targets. Two cruisers assisted with fire on the flank of the beachhead.
