ITEM. GDW has issued an errata sheet dated March 28, 1976, in which most
initial errata in Port Arthur and Tsushima is corrected. The following
questions are not covered in that errata sheet and should bring the
rules for the total set 'closer to home'. Mostly, these concern Port
Arthur.

Q. How many supply counters may be stacked in a hex?

A. Unlimited number. They do not count against combat unit stacking.

Q. Do supply counters retreat when a combat stack in the same hex is
retreated?

A. No.

Q. May supplies be captured? If so, WHEN and HOW?

A. Yes. Capture by moving into the same hex, in which no enemy units are
present.

Q. May you destroy your own supply counters to prevent capture & if so,
WHEN and HOW?

A. Yes. During Terminal Phase.

Q. If a defending unit is routed and retreats four hexes, may the
Attacker ADVANCE four hexes, or only occupy the Defender's hex?

A. Attacker may only advance one hex, and occupy vacated hex.

Q. Suppose I attack 'into' a stack, attacking a division but ignoring
two regiments. I achieve three hits. May the defender distribute these
three hits among the three units - even though only the division was
attacked?

A. No. By 'defending units', it means only the units actually being
attacked. A unit which was not attacked may not receive a 'Hit'.

Q. Fortress Movement Rules. Suppose Mukden is completely surrounded by
Japanese units (not ZOC's but a solid ring of combat units).
Nonetheless, on the previous turn, the Russian units arriving from
Harbin have managed to push and remain within four hexes of Mukden. May
these units now use the Fortress Movement Rule to 'hop' into Mukden?
Notice, they are always in supply; first from Harbin, then 'hop' into
Mukden for intrinsic supply!

A. No. Typo: 1st paragraph of Fortress Movement Rule, add 'in supply from the same fortress.'
