Trigger problems

[RipperJack]

Ok, i have a problem.
I am making mission, where you must raid town under enemy control before more enemies arrives whit boat. Boat will go beach near town, and those enemy soldiers inside boat unloads and join the battle. Everything goes great, but now i should end the mission. First, i made huge trigger what makes mission end when "East not present". However, if even one enemy flee from town, it makes mission awful to end. Other way was keep ending trigger small, but if you clear town before boat arrives, it ends mission too soon.

My objectives are:

1. Clear city soon as possible
2. Ambush that boat before it lands, or defend yourself at town.

Make another trigger over the area where the boat lands, east present, select Group and group it with the boat.

Ok, now i have 2 triggers. One for East not present, and another one for boat.
How i make mission end, when both of these triggers has activated ?

Make them both the same type of end. Eg, end #1 and end#1. That will create an 'and' effect.
