Blocking of Dunkirk Inner Harbour (Operation C.K.) (See Plan 4 and
Appendix Z)
The blocking of the inner harbour at Dunkirk was under the command of
Captain E. Dangerfield, R.N., and was carried out on two successive nights.
The operation was first timed to be carried out on the night 1st-2nd June, but
at 1808 on the 31st the Admiralty ordered its postponement.
On each night three blockships, escorted by a destroyer, an MA/S.B. and an
M.T.B., were employed. The blockships assembled in the Downs, and (as
usual) they were such crocks that one, the French built Emerald Wings (Govern-
ment Yard, Cherbourg, 1920) broke down soon after leaving Portsmouth for
the Downs and had to be towed back to harbour; a second could not keep up
with the convoy; and a third, the Moyle, developed defects which, however,
by dint of working on her all night, were remedied in time.
The ships finally employed on the night 2nd-3rd June were as follows :-
Vivacious (destroyer)
M.A/S.B. 7
M.T.B. 107
Blockships Westcove 2734 tons, built 1912
Edvard Nissen 2062 tons, built 1921.
Holland Dutch M.V. 895 tons, built 1923.
Early on the 2nd of June Admiral Nord asked that the blockships might be
sent over to arrive at the entrance to Dunkirk harbour at 0300 on the 3rd, the
latest hour at which they could enter on that night, by which time it was hoped
the evacuation would have been completed. During the afternoon of the 2nd
however, the Admiralty received a message from the Admiral postponing the
operation because the evacuation would not be completed that night. However,
the Admiralty still hoped to complete the evacuation and ordered the block-
ships to sail.
At 2030 on the 2nd the Vivacious, with Captain Dangerfield on board and
with M.T.B. 107 in tow and M.A/S.B. 7 in company, sailed from the Downs,
leading the three blockships, and proceeded to Dunkirk by Route Z. The
Holland, unable to maintain the 71 knots speed of the convoy, was soon lost
to sight astern. Nearing Dunkirk a tug (either the Sun X, Sun XI or Foremost
87), towing a very long line of boats, crossed her bows and still further delayed
her, but she eventually made contact with M.A/S.B. 7 and asked to be led
into the harbour. The other two blockships had anchored at 0230, and a
