Cape Laghi; at the northern extremity the corresponding
point is Cape Pali; the distance between these two points
is about fifteen miles. Two subchaser units, six boats,
were assigned as a screen to the Italian cruisers while the
bombardment was under way. One unit, three boats,
was stationed at Cape Pali, to the north, to prevent any
submarines leaving Durazzo from attacking the British
cruisers, which were to approach the scene of activities
from that quarter, and another unit, three boats, was
stationed off Cape Laghi. Thus the two critical capes
were covered against submarine surprises, and the attacking vessels themselves were effectively screened.
The Italian cruisers sailed back and forth for about an hour, blazing away at Durazzo, destroying shipping in the harbour, knocking down military buildings, and devastating the place on a liberal scale, all the time screened in this operation by our chasers. Meantime, unit B, commanded by Lieutenant-Commander Bastedo, had started for its station at Cape Pali. The Austrian shore batteries at once opened upon the tiny craft, the water in their neighbourhood being generously churned up by the falling shells. Meanwhile, the British cruisers, after steaming for a while east, turned south in order to take up the bombarding station which, according to the arranged programme, the Italian warships were about to abandon. The three screening chasers were steaming in column, No. 129, commanded by Ensign Maclair Jacoby, U.S.N.R.F., bringing up the rear. Suddenly this little boat turned to the right and started scampering in the direction of some apparently very definite object. It moved so abruptly and hastily that it did not take the time even to signal to its associates the cause of its unexpected manoeuvre.
On board No. 215 there was some question as to what should be done.
"Let's go," said Commander Bastedo. "Perhaps he's after a submarine."
No. 215 was immediately turned in the direction of the busy No. 129, when the interest of its officers was aroused by a little foamy fountain of spray moving in the water slightly forward of its port beam. There was no mystery as to the cause of that feathery disturbance. It was made by a periscope; it was moving with considerable
