b) |
Enemy traffic is to be observed before the mines are laid, so that, within the area ordered, they can be laid at points where greatest success can be expected. If it is not possible to observe the traffic, or if such observation does not yield any clues, aim at fouling the area around Ambrose Lightship and south of this. |
|
c) |
In all circumstances the Captain is to do his utmost to lay the mines as far inshore as possible, where they are most likely to be effective i.e. in "Ambrose Place". The alternative or outer area is only to be fouled when all attempts to lay in the area further inshore have failed and further attempts appear useless. |
