"I am going to the latrine, but I shall return!"There is a moment where a hero, such as a soldier of an elite commando force, barely escapes a high security headquarters with the help of fellow prisoners who have risked everything to help him escape, and now have to be left behind. However, the hero tells them just before he leaves something along the lines of, "Don't despair, because I'll be back for you all." After considerable struggle, the hero returns to his headquarters and has more adventures until he has convinced his superiors to attack the enemy's base. So, the soldier's unit returns to the villain's hideout in force and suddenly the prisoners hear the explosions and realize the soldier has returned as promised, and he's brought an army to liberate them! The trope name comes from General Douglas MacArthur's catch phrase after he fled the Philippines in 1942 when the Japanese invaded, vowing that he would come back in force to liberate the nation, which he did two years later during the Battle of Leyte with a hearty, "I have returned!"
