Mountain Division, which succeeded in driving the guerrillas before it as the division moved westward. Probing for gaps in the German front, a number of small guerrilla groups slipped through the line formed by the 297th Infantry Division and fled to the north; the remainder of the guerrilla force moved southward, into a stronghold west of the road Vasilikon–Permet–Tepelene.
Reaching the road on the fourth day of the operation, the mountain division rested and regrouped to climb the almost vertical slopes west of Permet the following morning. With escape to the north and south now blocked off, the remaining guerrillas were compressed into the mountain area about Kuc and eliminated in another three days of hard fighting. The terrain, honeycombed with caves, had to be searched carefully and the guerrillas had to be killed or captured in hand-to-hand fighting.
GEMSBOCK cost the guerrillas over 2,500 dead and prisoners, and a large stock of arms; German casualties for the operation were 120 killed and 300 wounded.
Three weeks after the close of GEMSBOCK, the XXII Mountain Corps took the field in Operation STEINADLER, to destroy the guerrilla forces threatening the Korca–Yannina and Yannina–Trikkala roads. (Map 8.) Attached to the corps for the operation were the 1st Mountain Division, a provisional division formed from elements of the Corps Group Salonika, and a number of security battalions. Estimates of the enemy strength were vague, but could probably be put at 6,000–8,000. Of considerable significance was the close liaison between these Greek guerrillas and the strong communist groups in Albania just across the frontier.
As a security measure, only the minimum number of commanders and staff officers were informed of the operational plan, while the troops were told they were assembling for a series of small-scale operations. Further steps to preserve the secrecy of the operation consisted of radio silence on the part of units moving into the area, small-scale troop movements in adjacent areas, and radio traffic from the light division below Arta indicating an attack farther south. The radio net operated by the guerrillas was monitored carefully to determine their reaction to these measures and to detect possible alerting of their units. Air reconnaissance was extended into Albania in order to allay guerrilla suspicions over unusual interest in the area.
Setting up its command post in the vicinity of Metsovan, the XXII Mountain Corps deployed the 1st Mountain Division along a line extending from that point to Yannina, Vasilikon, and Leskovic. Strongpoints and reinforced security units acting as a blocking force secured the road from Leskovic to the north and a junction with the Salonika Division Group near Korea. From a point east of Korca, the Salon-
