ambushers. Mines could be used to stop the lead vehicle, while a bridge to the rear could be blown to block the column's withdrawal.
On the day of the attack, the guerrillas occupied their hiding places before daylight and waited throughout the day. Telephone and telegraph poles along the road had been cut almost through, so that they could be pulled down with little effort just prior to the action, effectively eliminating any wire communication between the garrisons at Arta and Yannina. Large boulders had been rolled into position on the higher ledges and so placed as to require only a slight pressure to send them tumbling down onto the column halted below. The few machineguns were sited to allow enfilading fire the length of the column, while the gun crews had the protection of the stone ledges against flat trajectory fire from below.
The Italian column appeared at 1600 and was halted exactly as planned when the lead vehicle, a tank, was disabled by mines. The last vehicle, also a tank, was trapped when the bridge behind it was blown a minute later. The column commander became a casualty almost immediately, and the alarmed troops added to the confusion by firing their automatic weapons blindly at the ledges above. The only organized resistance, which caused a number of casualties to the attackers, came from the crew of the tank at the tail of the column; this vehicle was soon put out of action by a dynamite charge. After raking the column repeatedly with heavy fire, the guerrillas swarmed down onto the roadway and slaughtered the few dazed Italians remaining; no prisoners were taken. The supplies carried by the column were quickly loaded onto pack animals brought up for the purpose, while roadblocks secured the attackers against surprise by relief columns from Arta or Yannina.
As planned by the attackers, approaching darkness made pursuit impossible. A motorcycle platoon sent out from Arta to investigate the disruption of wire communications was stopped by fire at the roadblock south of the site of the ambush and no further relief was attempted until morning, by which time the guerrillas were safely away.
Although the supply column had been heavily armed, the Italian commander had made a mistake that was often to cost the occupation forces heavily—he had followed a fixed pattern in moving critical supplies along the same route at regular intervals, making it possible for the guerrillas to determine the schedule, the strength of the escort, and observe the practice of having the only armored vehicles at the head and tail. Such successful attacks emboldened the resistance forces and inclined recruits to join their ranks or to assist them in various other ways, such as reporting troop movements.
During July and August, Fortress Division Crete was sent to Africa, and redesignated the 164th Light Africa Division. In its place, the
