16. With the month of June more extensive sabotage was embarked
upon under British direction. A tunnel was blown up on the 1st
June at Kournovo on the Athens-Salonika line; six bridges, one
100 feet long, were destroyed on the 20th/21st June between Katerine
and Gravia; on the same night bridges on the Kozani-Servia road
were destroyed; a large steamer used for supplying Axis forces
in Crete was sunk in Piraeus harbour; finally, the Asopos Viaduct
was blown up, causing an interruption of the vital Athens-Salonika
line, estimated to take a minimum of two to three months to repair.
17. Axis counter-action met with little success. A drive in
the Parnassus area ended on the 8th June after several Italian
defeats, in one of which some 500 men were lost. In another action
on the 9th-10th June the Italians lost 700 men; the guerrillas
had few casualties, though many villages in Thessaly were destroyed
in reprisal. In Epirus another action was fought against the
Italians, and it appears to have been so successful that in early
July an additional Italian division had to be sent to that area
from Athens. The Italians were also heavily engaged in Western
Macedonia, while a German column was attacked near Kozani on
the 19th June.
18. During the last weeks there has been a considerable increase
in the Axis garrison of the mainland of Greece; the Italian divisions
have remained at 8; the Germans have, however, increased from
two in March to six, possibly seven, and, according to an intelligence
report Bulgarian control is to be extended in Macedonia, and
may perhaps embrace Salomka. It is unlikely that either the Germans
or, even more, the Italians would wish to see the Bulgars in
that city unless severely stretched themselves. It cannot, of
course, be claimed that the four additional German divisions
have been sent to Greece as a result of guerrilla action alone.
But there is evidence that those in Epirus and Northern Thessaly
were particularly intended to operate against the guerr %illas,
and even if the threat of an Allied invasion were removed, it
is improbable that the Germans could hope to reduce their forces
by more than three divisions.
19. British liaison officers state that there are approximately
20,000 armed mobile guerrillas in the field; in addition, a very
large proportion of the whole population would fight the Axis
in propitious circumstances if they could be armed and organised.

III.--ALBANIA.
20. Guerrilla activity in Albania has never assumed the proportions
seen in Yugoslavia and Greece, nor have the Axis forces there
ever exceeded about four divisions. A considerable quantity of
minor incidents have, nevertheless, occurred all over the country
since early in 1942. Hitherto these have not assumed proportions
which have called for serious military action by Italy, but early
in July the garrison of Premeti in Southern Albania was asking
urgently for reinforcements in view of a strong attack by guerrillas.
Incidents of this type would undoubtedly increase in degree and
in number as soon as more British liaison officers were infiltrated
and money and ammunition introduced. This is now in hand.
