The Time War 1

The Last Great Time War was the war between the Time Lords and the Daleks "for the sake of all creation". (TV: Gridlock) In a linear sense, it lasted for at least 400 years. Fought throughout countless time periods, however, it more accurately lasted an eternity as both sides fought across space and time, opening up new fronts as the Daleks seeded themselves in different epochs. (PROSE: Engines of War)

At the heart of the war, millions were killed and brought back to life every second, (TV: The End of Time) on account of both sides' manipulations. (AUDIO: Legion of the Lost) The Dalek forces numbered in the billions (TV: The Day of the Doctor) and fielded a fleet of ten million flying saucers. (TV: Dalek) The Time Lords used over a million Battle TARDISes. (PROSE: Peacemaker)

It resulted in the apparent destruction of Gallifrey, (TV: The Day of the Doctor) leaving only three Time Lords (TV: Utopia, AUDIO: Divorced, Beheaded, Regenerated) and a small number of Daleks as survivors. (TV: Dalek, Doomsday, et al.)

The Time Lords became aware of their future involvement in the Time War a long time before it began, and many prophecies, stories and legends were generated around the idea. One concerned the Hybrid, which some took to believe would be a creature, half-Time-Lord and half-Dalek, capable either of Gallifrey's salvation or destruction. Many years later, after the war, the Twelfth Doctor would claim that the Hybrid was destined to conquer Gallifrey and stand in its ruins. (TV: Heaven Sent)

The Time Lords foresaw the War during the life of the Eighth Doctor, as Straxus told the Doctor they saw "something terrible in the time tracks." (AUDIO: Fugitives)

Shortly before the war began, the Matrix prophesied that Gallifrey would be destroyed in a war, though there were other predictions that showed Gallifrey's destruction in other ways, (AUDIO: The Crucible of Souls) a time war. (AUDIO: Songs of Love)
