1. The following is an extract from Operation Order “M 1”, dated 5 June 1918, from the QUEEN ELIZABETH, signed by the Commander-in-Chief of the Grand Fleet.
“In the event of weather preventing minelaying, forces are
if practicable, to wait until a period of twenty-four hours has elapsed in case the weather should improve later and render minelaying possible. x x x x x
The decision as to postponement rests with the Rear Admiral (M), who in such an event is to make a cypher signal to Forces ‘B’ and ‘C’ --- ‘OPERATION POSTPONED 24 HOURS’. The operation is then, weather permitting, to be carried out exactly 24 hours later, the movements and time table laid down in paragraph 5 being adhered to.
“A decision whether or not the operation is to be attempted on the following day is to be made by the Rear Admiral (M), x x x x x. If necessary to postpone definitely the operation until a future occasion, the Rear Admiral (M) is to make a cypher signal---‘OPERATION CANCELLED, RETURN TO BASES’”.
2. The operation of laying mines in the North Sea, as designed, may separate the British and United States minelaying forces by as much as 150 miles and, as a matter of fact, during the operation for which this order was issued, they were separated before completing the work approximately 100 miles. The conditions of the North Sea are such as to make totally different weather conditions at a lesser distance. In fog especially is this true everywhere. I desire to invite attention to the fact that, should such an order be carried out, it might result in the failure of an operation where the work might well be proceeded with by one of the other of the mine forces.
