Sir Richard F. Crawford, British Commercial Attaché at Washington, to President Woodrow Wilson
My dear Mr. President: Washington June 29th 1917.
With reference to my letter of the 25th June I now have the honour to transmit the following supplementary information which has been received from London.
The total loss of tonnage (all vessels over 100 tons gross) by war risk from the beginning of the war till June 20th 1917 was approximately:
Great Britain 4,300,000
Allies (including the United
States of America) 1,343,000
Of this total the following loss was incurred between the beginning of February and June 20th 1917 (i.e. since the intensive submarine campaign)
Great Britain 1,800,000
Neutrals __ 628,000
This gives an average loss by war risk during this period of 636,000 gross tons per month. In addition about 34,000 tons per month may be taken as lost by marine risk, making a total (excluding damage without total loss) of 670,000 tons gross (or 1,117,000 tons dead weight) per month.
The above figures give gross losses without any offset for new building.
As against the loss Great Britain is building at the rate of 100,000 gross tons (or 170,000 tons deadweight) per month and the rest of the world outside America at not more than 40,000 tons gross (or 70,000 tons deadweight) a month altogether.
(The losses given include small coasting vessels which though important do not directly concern the main problem of maintaining overseas communications. Their total tonnage, however, is relatively small and the general results shewn above would be substantially unaffected if they were excluded.)
I may add in conclusion that should any further points for enquiry arise in connection with the information conveyed in the memorandum enclosed in my communication of the 25th instant Mr. Royden and Mr. Salter would be of course at your disposal at any time. I have mentioned this because these gentlemen I understand contemplate returning to England shortly.
With assurances of my highest respect,
I have the honour to be,
My dear Mr. President,
Yours faithfully, Richard Crawford.
