The French army in Belgium is bounced by the army from Yorkshire. The
army in London move to Belgium, dislodging the unit there.
The final destination of the army in the Yorkshire depends on how issue
4.A.7 is resolved. If choice a is taken, then the army advances to
London, but if choice b is taken (which I prefer) the army bounces and

For choice a, b and c the English army in Liverpool will move by convoy

For choice d, the 1982/2000 rulebook (which I prefer), the convoy
depends on the "intent". England intended to convoy via the French
fleets in the Irish Sea and the North Sea. However, the French did not
order the convoy. The alternative route with the Russian fleets was
unintended. The English fleet in the English Channel (with the convoy
order) is not part of this alternative route with the Russian fleets.
Since England still "intent" to convoy, the move from Liverpool to
Edinburgh should be via convoy and the two armies are swapped.
Although, you could argue that this is not really according to the
clarification of the 2000 rulebook.
When explicit adjacent convoying is used (DPTG, choice e), then the
English army did not receive an order to move by convoy. So, it is just
a head to head battle and both the army in Edinburgh and Liverpool will
not move.

For choice b and c, there is no unit moving in opposite direction for

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

def test_simple_convoy_paradox(self):
"""
The most common paradox is when the attacked unit supports an attack on
one of the convoying fleets.
England:
F London Supports F Wales - English Channel
F Wales - English Channel
France:
A Brest - London
F English Channel Convoys A Brest - London
This situation depends on how paradoxes are handled (see issue (4.A.2).
In case of the 'All Hold' rule (fully applied, not just as "backup"
rule), both the movement of the English fleet in Wales as the France
convoy in Brest are part of the paradox and fail. In all other rules of
paradoxical convoys (including the Szykman rule which I prefer), the
support of London is not cut. That means that the fleet in the English
Channel is dislodged.
