Battle rating $B = B' + n \lceil B'/10 \rceil$, where $n$ is the number of
matching statements.

\begin{itemize*}
\item 20\% of force is mounted.

\subsect{Other notes}
\begin{itemize}
\item PCs and major NPCs can be scattered but never killed in War Machine
  battles.
\item On losing side, all combat spells and two-thirds of offensive/defensive
  item charges used by PCs and major NPCs; on winning side, all but one
  combat spell, and one-third of item charges used.
\item XP for leading force: as number of opponents (win) or one-third (loss).
\item A \emph{staff of healing} immediately cures up to 500 wounded.
\item \emph{Casualties:} Half killed, half wounded.
\item \emph{Fatigue:} Seriously fatigued force becomes moderately fatigued
  after 1d4 days; moderately fatigued force recovers after 1d4 days.
\item \emph{Siege} (simple rules): Defender multiplies troop size by 4 for
  troop ratio; ignores retreat/rout; half casualties.  Attacker attacks
  normally, or \emph{besiege}: BR$^+$5 for each week; defender loses 10\% of
  numbers per week after exhausting food.
\end{itemize}

\subsect{Movement}
\begin{itemize}
\item \emph{Rate:} Let $V$ be the movement rate of slowest member of force.
  50 or fewer troops move at $V$; 51--100 move at $2V/3$; 101 or more move at
  $V/2$.  Cannot move if seriously fatigued.
\item \emph{Food:} Foraging at $2V'/3$ gives 2 in 6 chance of finding food,
  or $V'/3$ gives 4 in 6.  Two days without food causes moderate fatigue;
  three days causes serious fatigue; fatigue negated by day's food.
\item \emph{Forced march:} Move at $3V'/2$ if successful; see table -- `F' is
  successful forced march, `M' is moderate fatigue (serious if already
  fatigued), `S' is serious fatigue.
\item If one side uses `withdraw' and other does \emph{not} use `attack+',
  withdrawing side may move one terrain unit after combat; withdrawing forces
  cannot occupy field or pursue.

\sect{Siege machine}

\begin{multicols}{2}
\raggedright

\subsect{Attacker options}
\begin{itemize*}
\item \emph{Depart:} Leave battle; no combat.
\item \emph{Bombard:} Siege artillery (and ballista) fire only.
\item \emph{Harass:} Some siege equipment, artillery and missile fire.
\item \emph{Assault:} Full-scale attack, $+5\%$ to BR; defender casualties
  decreased by 5\%.
\end{itemize*}

\subsect{Defender options}
\begin{itemize*}
\item \emph{Depart:} If avenue of escape available; if 10\% of defenders
  remain, noticed after 1 turn of assault, 1d4 hours after dawn if harassing,
  unnoticed if bombarding.
\item \emph{Assault:} Full-scale attack, $+10\%$ to BR (for surprise, without
  fortification bonuses), choose time of attack, use standard \emph{War
  Machine} with tactics.
\end{itemize*}

\subsect{Preparation}
\begin{enumerate}
\item Compute weekly payroll, food, water, supplies and ammunition costs;
  note money, rations and ammunition on hand.
\item Compute BR for each side's forces.
\item Defender lists fortifications and visible siege engines; attacker lists
  visible siege engines; exchange lists.  Dimensions may be inaccurate by
  $5'$.  Invisible and concealed equipment need not be revealed.
\item Defender computes adjustments for all fortifications and siege
  equipment depending on attacker tactics:
  \begin{itemize*}
  \item \emph{Bombard:} Artillery bonus and half ballista bonus.
  \item \emph{Harass:} Double artillery bonus, full ballista bonus.
  \item \emph{Assault:} No artillery bonus, double ballista bonus.
  \end{itemize*}
\item Attacker computes adjustments for tactics:
  \begin{itemize*}
  \item \emph{Bombard:} Artillery bonus and half ballista bonus.
  \item \emph{Harass:} Ballista, timber fort and mantlet bonuses, and
    artillery if used.
  \item \emph{Assault:} All equipment bonuses, double ballista bonus, and
    artillery bonus if used.
  \end{itemize*}
\end{enumerate}

\subsect{Application}
\begin{enumerate}
\item Deduct costs for week.  Ruler under siege cannot receive dominion
  income.
\item Compute BR modifications; fatigue lasts one week.
\item Choose tactics and apply results.
  \begin{itemize}
  \item \emph{Bombard:} Let $A$ be the BR bonus for artillery and ballistas.
    Defender casualties are $A/10 \times \d{1d10}$ hit dice; attacker
    casualties are $A'/10 \times \d{2d10}$ HD.
  \item \emph{Harass:} As for \emph{War Machine}, except: casualties are 1/10
    of listed (1/20 for defenders), no location changes; artillery casualties
    computed as for bombarding, split 4/1.
  \item \emph{Assault:} As for \emph{War Machine}, except: casualties are
    half of listed (quarter for defenders), rout or extermination indicates
    defenders driven from fortification, or attackers to bombarding range;
    artillery casualties computed as for bombarding, split 3/2.
  \end{itemize}
\item Compute damage to fortifications; let $d$ be damage roll for
  all attacker siege devices used: damage is $d - \d{1d\%}$, applied to 75\%
  of walls, and then 20\% of:
  \begin{itemize*}
  \item gatehouses, gates, and drawbridges;
  \item normal buildings;
  \item towers;
  \item barbicans;
  \item keeps;
  \item walls and above list again.
  \end{itemize*}
  Concentrated fire: use at most 300 troops and 4 siege engines per $100'$ of
  fortifications; defender gains full BR from fortification and towers within
  $200'$, and one-quarter BR for other fortification.
\end{enumerate}

\subsect{Other notes}
\begin{itemize}
\item \emph{Food:} Rations available at half adventurer prices.  Moderate
  fatigue after one week of malnutrition, serious fatigue after two, loss of
  50\% BR after three; lose 2 points of morale per week; unfed troops desert
  after 1d3 days.  Mounts require double human rations.
\item \emph{Reclaiming ammunition:} All ballista ammunition is ruined by
  firing.  Defender reclaims one quarter of artillery ammunition fired by
  attacker.  Destroying stone buildings yields BR-value as weeks of
  ammunition.  Attacker reclaims three-quarters of ammunition used if
  bombarding, one-half if harassing or one-quarter if assaulting.
\item \emph{Ammunition conversion:} 6 units of light-catapult $=$ 5 units of
  heavy-catapult $=$ 4 units of trebuchet ammunition.
\item \emph{Field construction:} Equipment construction supervised by siege
  engineer (and artillerist, if applicable): a siege engineer can oversee
  four constructions at a time; an artillerist can oversee two.  Materials
  costs are 1/10 of listed equipment cost.  If $n$ men are within $d$ miles
  of wood source, wood for $5 \times \lfloor n/10 \rfloor \times \lceil d/5
  \rceil$~hp can be collected per day; one (untrained, supervised) man can
  construct $\tfrac{1}{2}$\,hp of equipment per day, max 9 men per item.
