Retreat Rules

Rules of Diplomacy

Copyright (c) Hasbro, Inc.

A unit which otherwise would have remained in the space attacked by a better supported unit is dislodged and must retreat or be disbanded.

It must move to a space to which it could ordinarily move if unopposed by other units; that is, to an adjacent space suitable to an army or fleet, as the case may be. The unit may not retreat, however, to any space which is occupied, nor to the space its attacker came from, nor to a space which was left vacant due to a standoff on the move. If no place is available for retreat, the dislodged unit is "disbanded"; that is, its marker is removed from the board.

Writing Retreats.

If two or more units must retreat after a move, the retreats are written down immediately by the players concerned, without diplomacy,

Other Retreat Rules.

A player may choose to disband a unit rather than retreat it.

If two or more units may retreat only to the same space, they are all disbanded, unless only one of the units is ordered to retreat and the others are ordered to be disbanded. In that case, the one unit ordered to retreat may do so. If two or more units are ordered to retreat to the same space, they are all disbanded.

If a player fails to order a retreat when necessary, the unit is disbanded. Retreats may neither be convoyed nor supported.

Diplomacy Adjudicator

Ken Lowe

The format of your Diplomacy orders depends on the phase of the game: Movement, Retreats or Adjustments. Multiple orders can be entered on one line by separating them with commas or semicolons.

Retreat orders:

{type} {s-prov} {moves}   {d-prov}
{type} {s-prov} {disband}
{/pre}
where:
{pre}
{type}    = "army", "a", "fleet", "f" or {empty}.
{s-prov}  = Source province.
{moves}   = "-", "->", "m", "move", "moves", "move to", or "moves to".
{d-prov}  = Destination province.
{disband} = "d" or "disband"

Diplomacy Programming Project Protocol

The following messages are used in the retreat phase by the Diplomat Adjudicator. Note that all dislodged units must submit an order even if there is no option other than disband. For consistency, an "empty" retreat phase is automatically generated if no units must retreat.

Orders:

RTO prov            {retreat}
DSB                 {disband = nonretreat}

Used by diplomats to submit retreats, used by interface to display the results of a retreat phase (ord), used between diplomats to suggest or forbid retreats.

Notes:

1.  BNC             {move bounced, e.g.: eng-nth vss nwy-nth}
                    {...or retreat bounced, mutual disband}
2.  (RET prov)      {must retreat due to attack from (prov)}
3.  (note RET prov)
4.  (MBE {[provs]}) {retreat is no good, it must be to one}
                    {of the following provinces}
5.  NRN             {no retreat needed for this unit}
6.  NRS             {not right season}

used by interface to indicate (1,2,3,4) the result of moves made (ord) or (5,6) moves illegally submitted (thk). NRS is also used to forbid diplomacy prior to retreat phases.
