Defeat

Temmosus voiced his surprise at how often apparent defeat could be turned to victory. (TV: The Daleks)

General Staal of the Tenth Sontaran Battle Fleet introduced himself as "Staal the Undefeated", to which the Tenth Doctor pointed out that such a title would no longer be accurate if he did get defeated, joking, that, that would make him "General Staal the Not-Quite-So-Undefeated-Anymore-But-Never-Mind." (TV: The Sontaran Stratagem)

Davros deemed the transference of the Twelfth Doctor's regeneration energy into himself and the Daleks to be the "final defeat of the Time Lords". (TV: The Witch's Familiar)

Special Weapons Daleks
The Dalek Survival Guide recorded what it deemed to be the five greatest defeats incurred by Special Weapons Daleks, as well as their greatest victories.

Special Weapons Daleks were deployed to Lopra Minor to act as ground troops. Airborne Special Weapons Daleks were later used to breach Lopra Minor's defences and gain access to Project Infinity. (AUDIO: Project Infinity) A final assault against the Daleks was led by Knight of Velyshaa Kalendorf, commanding Earth Alliance forces aboard Battlecruiser Courageous. Armed with information gleaned straight from the Dalek command net, a nest of attacking Airborne Daleks were wiped out by sub-orbital assault craft. The Dalek Survival Guide counted this as the fifth greatest defeat of the Special Weapons Daleks.

In the Handroz asteroid belt, a vast force of Special Weapons Daleks were detected hiding in the asteroid belt. Gravitraction stasis mines were used to crush the entire belt to the size of a small refrigeration unit. The Dalek Survival Guide counted this as the fourth greatest defeat of the Special Weapons Daleks.

In the AKG04 sabotage gambit, an operative, known only as AKG04 for security reasons, managed to isolate the command frequencies of the Logril 9 Dalek Division's Standard SWD Minder. For several years, this enabled the selective transmitting of false and contradictory commands to Special Weapons Daleks. Famous amongst these commands were "You are very tired - shut down for a short sleep", "What was that noise behind you?" and "Human beings are now your friends, cease firing". The Dalek Supreme ultimately had the frequencies altered and issued orders for the conditioning of Special Weapons Daleks to include the annihilation of concepts such as tiredness, friendship and curiosity. The Dalek Survival Guide counted this as the third greatest defeat of the Special Weapons Daleks.

In the Garazone campaign, scientists cleverly synthesised the schrellic gland's secretions, luring 50 squadrons of interplanetary Airborne Daleks into a trap. The potency of the schrellic substitute was such that the first 27 squadrons willingly flew into the Garazone sun. The Dalek Survival Guide counted this as the second greatest defeat of the Special Weapons Daleks.

On Oceanaron, the sea moon of Kelados, a low-level chemical weapon bombing raid transformed the planetoid's oceans into highly corrosive acid, thus destroying the flotilla of Torpedo Daleks who had not-so-cunningly disguised themselves as rather large floating mounds of Dalek-shaped Keladon gull dung. The Dalek Survival Guide counted this as the greatest defeat incurred by Special Weapons Daleks. (PROSE: Dalek Survival Guide)
