That picture doesn't reveal too much, aside from the fact that it happened.
Was your Bomber stationed in Paris? If so, then the reason for the loss to a Pikeman is fairly simple. There wasn't a unit there in Paris to defend it. If an air unit is stationed in a friendly city, but attacked by an land-based enemy unit, then it will always lose. To avoid this, you must provide a defensive unit of your own in order to protect the air unit. You cannot rely on an ally's defender to protect air or naval units.
The same thing happens to naval units when attacked by land units.
The exception to this would be if your ally/open borders civ is also at war with the same civ as you, and the enemy attacks your ally's city. In that scenario, the ally's defenders will be attacked before your bomber.
