Deluge II
by Tim Sharrock and Stephen Agar
[Amendments in square brackets by Dylan O'Donnell]

[Abstraction A/F rules stolen wholesale from Box Frenzy's
website (now apparently defunct).]

This set of rules are a considerable improvement over and above the
original rules published originally in He's Dead Jim No.17.  Many of the
changes included here were discussed by myself with Tim Sharrock (the
original designer) back in 1979, others stem from comments made by Denis
Jones in Surfa Rosa 5, and yet others are refinements of my own.
Abstract A/F rules are available on request in return for a SAE.

0. Regular Diplomacy rules apply except when they don't.

1. The game begins in Winter 1900 which is played as a separate season..
Players may decide which type of unit to build in their home centres in
readiness for Spring 1901. Russia may build F(StP)nc if it wishes.

2. Any army in a coastal province may, instead of being ordered to move
or support, be ordered to turn into a fleet.  Such a transformation will
be successful provided the unit is not dislodged that move.
[written as, eg, "A Yor converts"]

3. Rising sea levels result in the gradual submergence of  provinces
according to Table 1 below.  Submergences occur every  year after any
adjustments in Winter.  Once submerged, a s.c. is  effectively destroyed
and may not be used for the following  Winter's adjustments.

Table 1 - Submergences

W 1901: Lon, Hol, Bel, Gas, Ven, Lvn.
W 1902: Yor, Pic, Apu, Rum, Sev, Fin, Syr, Den, Lpl.
W 1903: Arm, Bre, StP, Par, Tus, Nap, Bud, Kie.
W 1904: Ber, Mos, Mar, Por, Rom, Vie, Bul, Gre, Pru, Ruh, Gal, Ukr, Con
W 1905: Wal, Cly, Swe, Tri, Alb, War, Ice
W 1906: Edi, Spa, Tun, Ser, Smy, Sil, Boh.
W 1907: Nwy, Mun, Pie, Tyr, NAf, Bur, Ank.

4. Armies in provinces which submerge are drowned!

5. New supply centres are formed in the course of the game, after all
Winter retreats and adjustments, according to Table 2.

Table 2 - New Supply Centres

W 1901: Wal, Ruh, Tyr.          
W 1902: Ukr, Ice
W 1903: Pie.    
W 1904: Boh, Sil.
W 1905: Swi
W 1906: NAf

When a new s.c. is created it immediately comes under the  control of
(1) any unit occupying that province, (2) the last  country to have a
unit in that province (spring or autumn), (3)  the country within whose
boundary the new s.c. lies or (4) if  none of the above it is neutral.

6. Iceland is a valid space in this variant and it becomes passable
after W 1901. The province of Switzerland becomes passable after W 1904.

7. Players may build units in any vacant supply centre which they
control.

8. As per Deluge I, all Abstraction A/F convoy rules apply. [See below]

9. The winner is the survivor  (if any) after W 1908.

Abstraction A/F Rules (devised by Fred C. Davis jr)

1.The Fast Ferry. Convoy by the standard Diplomacy means is only allowed if it
  covers the crossing of a single sea space. This one space convoy will be 
  referred to as the Fast Ferry and the order for its use is "FF". A fleet
  may FF an army of any nationality. If the army does not succeed in its 
  disembarkation, then it stays aboard the fleet to become an Army/Fleet 
  (A/F). If the units belong to different powers, the army must return to its 
  starting position because multi- national A/Fs are not allowed. 
[Fast Ferry may also be referred to as "convoy", abbrev. "c"; no scope for
confusion with conversion, since only fleets may convoy, only armies may
convert.]

2.Army/Fleets. All convoys involving the crossing of more than one sea may 
  only be undertaken by the formation of an A/F to carry the army "piggy-back".
  On a given move, an army in a coastal province adjacent to a sea space 
  containing a fleet may be placed aboard that fleet, to form an A/F. The A/F 
  may then move to another sea space, and may then also disembark the army 
  into a land province bordering the second sea space. 

           EG  A(Mar) E F(GOL);  A/F(GOL) - WMS;  A(WMS) D Tun.
                 (E = Embarks;  D = Disembarks)

     An A/F may only consist of two units belonging to the same country. 

3.Army/Fleet Combined Operations. An A/F has the same "combat factor" as a 
  single fleet; it may attack, support or be supported. It cannot convoy 
  another army via the FF. An A/F can only exist in a sea space - it cannot be
  ordered to a coastal province as an entity - but it may support some other 
  unit into a coastal province. If an army is ordered to board a fleet, and 
  the A/F is prevented from moving to another sea space the A/F remains intact.
  An A/F may be ordered to stand. 

  If an army is ordered to board a fleet, and the fleet is attacked from 
  another sea space, or if the fleet is ordered to support another unit, the 
  army is considered to have failed to board and it remains in its land 
  province. This is true even if the fleet successfully defends itself against
  attack. 

  A fleet which lands an army in a coastal province, before making a move, 
  may then support that army to land as its move, or it may move elsewhere. 
  If an army's disembarkation fails, the A/F remains intact and any orders for
  fleet movement will not be carried out. A fleet may not simultaneously land 
  one army and pick up another. If an A/F is annihilated, then both units are 
  removed from the board. 

  By way of explanation all the following are possible in one given move: 

          
           A(Lon) E F(ENG); A/F(ENG) - MAO; A(MAO) D Por. 
           A/F(ENG); A(ENG) D Bre; F(ENG) - NTH. 
           A/F(ENG); F(ENG) S A(ENG) D Bre.
           F(ENG) FF A(Lon) - Bre.
          
           But not  A(Lon) E F(ENG); F(ENG) S A(Lon) - Bre.

4.Retreats, Dislodgements and Annihilation. If an A/F is dislodged whilst 
  trying to disembark its A, this move fails and the A and F must retreat 
  together. If an A/F is dislodged and can only retreat to a land space (no
  suitable sea space being available), the F may retreat but the A is 
  destroyed. 

  Where an A disembarks from the F, and the F then moves away without 
  supporting the A; if the now vacated sea space is then occupied by another 
  unsupported F or A/F, the A disembarkation succeeds; if the second
  occupation is supported, the disembarkation fails and the A continues with 
  the F.
