            are not English. It will take the convoy via the North Sea anyway and the army in London will end in
            Belgium. However, when the 1971 rules are used, the situation is different. Since both the fleet in the
            English Channel as the fleet in North Sea are not English, it can not be concluded that the German fleet
            is "unwanted". Therefore, one of the routes of the convoy is disrupted and that means that the complete
            convoy is disrupted. The army in London will stay in London. See also issue 4.A.1.

            When the 1982 rule is used about multi-route convoy disruption, then convoys are disrupted when all routes
            are disrupted (this is the rule I prefer). With this rule, the situation becomes paradoxical. According to
            the 1971 and 1982 paradox rules, the support given by the fleet in Naples is not cut, that means that the
            fleet in the Tyrrhenian Sea is dislodged.

            support of Naples is cut and the fleet in the Tyrrhenian Sea is not dislodged.
            If the Szykman rule is used (which I prefer), the 'All Hold' rule or the DPTG, then there is no paradoxical
            situation. The support of Naples is cut and the fleet in the Tyrrhenian Sea is not dislodged.

            If the 1971 rule is used about multi-route convoys (when one of the routes is disrupted, the convoy fails),
            the Italian convoy order in the Ionian Sea is not part of the convoy, because it is a foreign unit
            (according to the DPTG).
            That means that the fleet in the Ionian Sea is not a 'convoying' fleet. In all rulings the support of
            Naples on the Ionian Sea is cut and the fleet in the Ionian Sea is dislodged by the Turkish fleet in the
            Eastern Mediterranean. When the 1982 rule is used about multi-route convoy disruption, then convoys are
            disrupted when all routes are disrupted (this is the rule I prefer). With this rule, the situation becomes
            paradoxical. According to the 1971 and 1982 paradox rules, the support given by the fleet in Naples is not

            cut and the fleet in the Ionian Sea is dislodged by the Turkish fleet in the Eastern Mediterranean.
            If the Szykman rule, the 'All Hold' rule or DPTG is used, then there is no paradoxical situation. The
            support of Naples is cut and the fleet in the Ionian Sea is dislodged by the Turkish fleet in the Eastern
            Mediterranean. As you can see, the 1982 rules allows the Italian player to save its fleet in the Ionian Sea
            with a trick. I do not consider this trick as normal tactical play. I prefer the Szykman rule as one of the
            rules that does not allow this trick. According to this rule the fleet in the Ionian Sea is dislodged.

            In all rulings, except the 1982 paradox ruling, the support of the fleet in Clyde on the North Atlantic
            Ocean is cut and the French fleet in the Mid-Atlantic Ocean will dislodge the fleet in the North Atlantic

            As you can see, the 1982 rule allows England to save its fleet in the North Atlantic Ocean in a very
            strange way. Just the support of Clyde is insufficient (if there is no convoy, the support is cut). Only
            the convoy to the area occupied by own unit, can do the trick in this situation. The embarking of troops
            in the fleet deceives the enemy so much that it works as a magic cloak. The enemy is not able to dislodge
            the fleet in the North Atlantic Ocean any more. Of course, this will only work in comedies. I prefer the
            Szykman rule as one of the rules that does not allow this trick. According to this rule (and all other

            Russia: A Sweden - Norway
            See issue 4.A.3.
            For choice a, b and c the move of the army in Norway is by convoy and the armies in Norway and Sweden are
            swapped. If the 1982 rulebook is used with the clarification of the 2000 rulebook (choice d, which I
            prefer), the intent of the English player is to convoy, since it ordered the fleet in Skagerrak to convoy.
            Therefore, the armies in Norway and Sweden are swapped. When explicit adjacent convoying is used (DTPG,
            choice e), then the unit in Norway did not receive an order to move by convoy and the land route should be
            considered. The Russian army in Sweden is dislodged.

            Since England ordered the army in Norway to move explicitly via convoy and the army in Sweden is moving
            in opposite direction, only the convoyed route should be considered regardless of the rulebook used. It
            is clear that the army in Norway will dislodge the Russian army in Sweden. Since the strength of three is
            in all cases the strongest force. The army in Sweden will not advance to Norway, because it can not beat
            the force in the Norwegian Sea. It will be dislodged by the army from Norway.
            The more interesting question is whether French fleet in the Norwegian Sea is bounced by the Russian army
            from Sweden. This depends on the interpretation of issue 4.A.7. If the rulebook is taken literally
            (choice a), then a dislodged unit can not bounce a unit in the area where the attacker came from. This
            would mean that the move of the fleet in the Norwegian Sea succeeds However, if choice b is taken
            (which I prefer), then a bounce is still possible, when there is no head to head battle. So, the fleet in
            the Norwegian Sea will fail to move.

            If for issue 4.A.3 choice b or c has been taken, then the army in Gascony will not move with the use of
            the convoy, because the army in Marseilles does not move in opposite direction. This immediately means that
            the army in Marseilles may not move to Gascony when it dislodged by the army there.
            For all other choices of issue 4.A.3, the army in Gascony takes a convoy and does not pass the border of
            Gascony with Marseilles (it went a complete different direction). Now, the result depends on which rule
            is used for retreating (see issue 4.A.5).
            I prefer the 1982/2000 rule for convoying to adjacent places. This means that the move of Gascony happened
            by convoy. Furthermore, I prefer that the army in Marseilles may retreat to Gascony.
