During the Battle of Britain early in the Second World War, the St.
Mellon's Golf and Country Club, located in Monmouthshire, adopted a set of
unusual rules for unusual circumstances.

Written by B. L. Edsell, the club secretary, they read:

1 - Players are asked to collect the bomb and shrapnel splinters to
prevent their causing damage to the mowing machines.

2- In competition, during gunfire or while bombs are falling, players may
take shelter without penalty for ceasing play.

3 - The positions of known delayed-actions bombs are marked by red flags
at a reasonable by not guaranteed safe distance therefrom.

4 - Shrapnel and/or bomb splinters on the fairways or in bunkers within a
club's length of a ball may be moved without penalty, and no penalty shall
be incurred if a ball is thereby caused to be moved accidentally.

5 - A ball moved by enemy action may be replaced, or if lost or destroyed,
a ball may be dropped without penalty, not nearer the hole.

6 - A ball lying in a crater may be lifted and dropped not nearer the
hole, preserving the line to the hole, without penalty.

7 - A player whose stroke is affected by the simultaneous explosion of a
bomb may play another ball under penalty of one stroke.
