Mine-laying order "New York"
for U 87
_______________________
       
     
MS note: Later Naval War Staff (1st Div.) would not approve this, as diplomatic ships were still sailing.  "Boston" was the alternative.
       
I. a) "Ambrose Place" is to be extensively fouled with mines.  If this is not possible "Alternative Ambrose Place" is to be fouled.  If, after repeated efforts, even this latter cannot be done, fouling is to be done in "New York Outer Place" (see diagram).
 
 
- 76 -
     
     

 

     
     
 
  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.
       
II. a) "Ambrose Place" lies within the following points:
     
400 27' N 730  55' W   400 30' N 730  49' W
400 28' N 730  45' W   400 23' N 730  54' W
  b) The boundaries of "Alternative Ambrose Place" are E and S the circumference of a circle having its center off light and bell buoy 2A (400 30' N    730  56' W), NW a line from Long Beach off 730  41' W    and a point on the coast from New Jersey off 400 23' N.
  c) "New York Outer Place" lies within the circumferences of circles and 22 sea miles from light and bell buoy 2A.
       
III.  Material:  10 TMC, time setting 60 days, delay clockwork 2 days, sensitivity 10 milliorsteds, to fire at first crossing, 5 mines with "BIK rot" (magnetic firing unit, south polarity), 5 mines with BIK blau (magnetic firing unit with North polarity).  Mines should be laid at a depth of 20-30 meters, minimum distance apart 1000 meters.
       
IV. a) Chart D 455 is to be taken.
  b) See Standing War Order 492, para 2.
       
V.  A report is to be made as soon as possible after laying, but from at least 50 sea miles away from the place of laying, by short signal.  The following groups to be used:
  LTIQ    =  "Ambrose Place" fouled
  LTGO:  =  "Alternative Ambrose Place" fouled
  LTJR    =   "New York Outer Place" fouled.

- 77 -
     
     

 

     
     
 
    If this is not possible "Alternative Overfalls Place" is to be fouled.  If, after repeated efforts, even this latter cannot be done, fouling is to be done in "Delaware Outer Place".  (see diagram).
  b) (See page 16 I b).
  c) (See page 16 I c. for "Ambrose Place" read "Overfalls Place".)
       
II. a) "Overfalls Place" lies within the points:
     
380 45' N 750  02' W   380 48' N 740  57' W
380 45' N 740  53' W   380 42' N 740  59' W
  b) "Alternative Overfalls Place" is bounded:  In the NW and N by a line from Rehoboth through a point 380 51' N    740  52.3' W to a point 380 51' N    740  47' W, in the E and S by the circumference of a circle of 15 sea miles diameter, having as its center Cape Henlope (380 47.8' N    750  05.5' W).
  c) "Outer Delaware Place" lies between the circumferences of circles of 15 and 23 sea miles diameter around Cape Henlope.  The N. limit is latitude 380 51' N.
       
III.  Material:  15 TMB, time setting 60 days, delay clockwork 2 days, sensitivity 20 milliorsteds, to fire at first crossing, about half the mines with "BIK rot", the rest with "BIK blau".
  Mines should be laid at depth of 15-22 meters.  Minimum distance apart 1000 meters.
       
IV. Chart D 457 is to be taken. See Standing War Order 491, para. 3.
