The Second War (Warcraft 2)
The isolationist elves took little interest in the events of the Second War. Nevertheless, they provided the Alliance of Lordaeron with token support, for the last descendent of King Thoradin, Lord Anduin Lothar, commanded the Alliance military forces. The high elves had not forgotten their pledge.
Then the Horde recruited Amani trolls into its ranks. Shortly thereafter, the Horde burned down the borderlands of Quel'Thalas and slaughtered many high elf civilians. Furious at this wanton destruction of life, the elves subsequently committed all their resources to the war.

By the time the Horde was driven back, however, the orcs and trolls had already achieved their true goal: to steal and desecrate many of the Runestones that powered the elves' defensive shield. The warlock Gul'dan then used the pilfered stones to power his devious Altars of Storms.
Nevertheless, the Alliance ultimately won the Second War, and most of the vanquished orcs were rounded up and placed in internment camps. In the war's aftermath, the cost of rebuilding was significant, particularly when added to the cost of maintaining the internment camps. Without a common enemy, the human nations began bickering over territorial claims. To make matters worse, the high elves abruptly seceded from the Alliance, blaming the humans' poor leadership for the burned forests of Quel'Thalas. High elves gradually grew further and further apart from their human and dwarven allies.
