ika force was responsible for the line Bilisht–Kastoria–Neapolis–Grevena–Krania–Metsovan.
Aware of their predicament as soon as the German troops had detrucked, the guerrillas evacuated Pendalofon and moved into the mountains. Air reconnaissance reported them still within the encirclement, however, and the troops continued their movement as planned. The first day ended with elements of the 1st Mountain Division held up by stiff resistance north of Metsovan. During the day, troops of the Salonika Division Group repulsed an attempt by a strong guerrilla force to break out at Grevena.
On the second day, the Salonika Division Group was forced to halt and reorganize, having found it difficult to maintain cohesion over the rough terrain. The 1st Mountain Division, meanwhile, became heavily engaged at close quarters when it attempted to break through the resistance to its front. It was in this engagement that a battalion aid station, moved too far forward, was overrun by the guerrillas and eighty wounded were murdered and mutilated.
On its left, the 1st Mountain Division managed to forge ahead and on the third day enveloped the guerrilla pocket north of Metsovan, only to find a large part of the defending force had escaped to the northwest. Some 1,500 guerrillas were compressed in a ring about Pendalofon and destroyed in a systematic combing operation lasting two more days.
STEINADLER cost the Greek guerrillas a total of 567 dead and 976 prisoners. In addition, 341 Italians and seven Britons were also captured. The booty taken included 10 tons of explosives, over three quarters of a million rounds of rifle and machinegun ammunition, and 10,000 head of livestock, mostly sheep and goats. Despite these losses, the guerrilla forces began to regroup as soon as the German combat troops had left the area.
