Solutions

1.  THE ATTEMPT TO ESTABLISH BASES FAILED

2. Here there are the Pins and lugs values of each wheel:
   Wheel 19:  0 0 3 0 3 0 3 3 0 3 3 0 3 3 3 3 3 0 3 
   Wheel 17:  1 1 0 0 0 1 0 0 1 0 1 0 1 0 0 0 1

3. ALLIED SHIPS WERE FORCED TO RETREAT

4. THE MARINES ASHORE WITHOUT MUCH OF THE HEAVY EQUIPMENT

   Key List:

     Wheel 19: Lugs:5, Pins: _BC_EF___J__M_OP_RS

5. THE SHIPS WERE PROTECTED BY TWO TASK GROUPS  

     Wheel 19, Lugs:5, Pins: _____FGHIJ__MNO__RS
     Wheel 17, Lugs:4, Pins: ABC_E_G_IJ___NOPQ

6. EARLY IN THE MORNING FIVE DESTROYERS DELIVERED ARMY TROOPS

   Key list:
     Wheel 19: Lugs=2, Pins= __C_E_G____LM_OP_RS
     Wheel 17: Lugs=7, Pins= __CD___H_J_LM___Q

7. THE ADMIRAL DECIDED TO WITHDRAW NAVAL FORCES


8.
   No. 1 - THAT NIGHT TWO GROUPS WERE SURPRISED 
           AND DEFEATED BY ENEMY  
   No. 2 - FIVE DAYS WORTH OF FOOD HAD BEEN LANDED
           FROM THE TRANSPORTS

   Wheel 26, Lugs=6, Pins: AB_DE_GHI_____OP_R___V__YZ
   Wheel 25, Lugs=7, Pins: A____FGHI__L_N__QR__UVX__

9. WE OVERWHELMED THE DEFENDERS  

   Wheel 23: Lugs:3, Pins: __CD_F__IJKLM__PQ_S__V_
   Wheel 21: Lugs:5, Pins: _____FG_IJK__NO_QR_TU
   And 2 overlaps

10. THE SUPPLIES WERE MOVED FROM THE LANDING BEACH    

   Wheel 21: Lugs:7, Pins: _B__EFGHI_K__NO____TU
   Wheel 17: Lugs:1, Pins: A_CD_____JKLM___Q

11. IN THE BATTLE THREE CRUISERS WERE SUNK AND 
    TWO DESTROYERS WERE DAMAGED

   Key list:
    Wheel 25, Lugs:12, Pins: A___EF__I_K_M___Q__TU_XYZ
    Wheel 17, Lugs:3,  Pins: AB_DE__H___LM___Q
    Overlaps: 1

   Message Keys:
    No 1 : LH
    No 2 : AA

12. 
   No. 1 - THE z DEFENDERS z WERE z ALL z KILLED z
   No. 2 – z THE z DEFENDERS z WERE z ALL z KILLED
