First, calculate all possible losses for each stack, and then display a message if there are any.

local enemieskilledcounter = 0            
n_stacks = GetSavedCombatArmyCreaturesCount( combatIndex, 0 );
for i = 0,(n_stacks-1) do
  local revenge_target, count, died = GetSavedCombatArmyCreatureInfo( combatIndex, 0, i );
  if revenge_target == 112 and died >= 1 then
    enemieskilledcounter = enemieskilledcounter + died;
  end
end
if enemieskilledcounter > 0 then
  ShowFlyingSign({GetMapDataPath().."Duncan_Counter.txt"; showcounter=enemieskilledcounter}, "Duncan", 1, 10)
end
