Diplomacy - failed attack
We have

Austria
  F Ion-Gre

Turkey
  F Aeg-Gre

Italy
  F EMa-Aeg

F Ion-Gre bounces with F Aeg-Gre because both have strength 1 so nobody wins.   As a result the fleets never leave their spaces and thus F Aeg stays at Aeg.

So F EMa-Aeg attacks an occupied space. Both have strength 1 so both stay at their spaces with the end result that nothing changes.
