THE BRITISH PATROL OFF NEW YORK
I have felt uncomfortable about this for some time. Although it is strictly legal, it must be very galling to the Americans to see their capital port picketed in this way. Instructions should be given that the patrolling cruisers should usually keep 8 or 10 miles away, or even farther if possible, and should only close in occasionally when there is some special need. They should, above all, be careful never to infringe the 3–mile limit, and should discharge their duties with tact, remembering how greatly British interests are concerned in the maintenance of good relations with the United States. On the other hand, the closest watch should be kept on shore upon the Hamburg-American liners, and our cruisers should be given the earliest warning if these are seen to be getting up steam. It ought to be quite easy to give our cruisers full warning of any movement. The prevention of these Hamburg-American liners leaving armed and fuelled is practically the whole duty of our vessels off New York; and as long as they are in a position to discharge this they need not be too obtrusive in their other duties.
ANTI-SUBMARINE MEASURES
It is intolerable that we should be told that Dover is not safe against submarine attack. It is the only military harbour we have except Portland. We must be able to keep ships there safely. Measures are being taken to close one of the entrances by sinking two ships. This is urgent and vital, and should be pressed forward from hour to hour without a moment’s pause. The other entrance should have an anti-submarine net and gate arranged. If the boom defence has carried away it must be repaired and replaced by night-and-day exertions. Meanwhile the long barges fitted with nets which have been prepared at Dunkirk should be brought over as soon as the weather allows, and used either to block the entrance or to give net-protection to ships lying inside.
