For choice b and c, there is no unit moving in opposite direction for
the move of the army in Picardy. For this reason, the move for the army
in Picardy is not by convoy and succeeds over land.
When the 1982 or 2000 rules are used (choice d), then it is not the
"intent" of the French army in Picardy to convoy. The move from Picardy
to Belgium is just a successful move over land.
When explicit adjacent convoying is used (DPTG, choice e), the order of
the French army in Picardy is not a convoy order. So, it just ordered
over land, and that move succeeds.
This is an excellent example why the convoy route should not
automatically have priority over the land route. It would just be
annoying for the attacker and this situation is without fun. I prefer
the 1982 rule with the 2000 clarification. According to these rules the

If for issue 4.A.3, choice b, c or e has been taken, then the move from
Sweden to Norway is not a convoy and the English fleet in Norway is
dislodged and the fleet in Skagerrak will not be dislodged.
If choice a or d (1982/2000 rule) has been taken for issue 4.A.3, then
the move from Sweden to Norway must be treated as a convoy. At that
moment the situation becomes paradoxical. When the 'All Hold' rule is
used, both the army in Sweden as the fleet in the North Sea will not
advance. In all other paradox rules the English fleet in the North Sea
will dislodge the Russian fleet in Skagerrak and the army in Sweden
will not advance.
I prefer the 1982 rule with the 2000 rulebook clarification concerning
the convoy to adjacent places and I prefer the Szykman rule for paradox
resolving. That means that according to these preferences the fleet in
the North Sea will dislodge the Russian fleet in Skagerrak and the army

First it should be mentioned that if for issue 4.A.3 choice b or c is

because the army in Venice is not moving in opposite direction. In that

the Austrian attack is considered to be coming from the Adriatic Sea,
then the support is cut and the army in Trieste will not be dislodged.

When a fleet of a convoy with multiple routes is dislodged, the result
depends on the rulebook that is used.
England:
F English Channel Convoys A London - Belgium
F North Sea Convoys A London - Belgium
A London - Belgium
France:
F Brest Supports F Mid-Atlantic Ocean - English Channel
F Mid-Atlantic Ocean - English Channel
The French fleet in Mid Atlantic Ocean will dislodge the convoying
fleet in the English Channel. If the 1971 rules are used (see issue
4.A.1), this will disrupt the convoy and the army will stay in London.
When the 1982 or 2000 rulebook is used (which I prefer) the army can
still go via the North Sea and the convoy succeeds and the London army
will end in Belgium.
