Exxilon Gambit
From Tardis Wiki, the free Doctor Who reference
The Exxilon Gambit was the final action of the Third Dalek War.
It was a form of germ warfare that entailed the Daleks infecting the Outer Worlds. The colonists that lived on the Outer Worlds discovered that parrinium could cure the germ.
A squad of Daleks had prepared for this, and so went to Exxilon, in an attempt to turn the tide of the war, (PROSE: The Secret Lives of Monsters) but they ended up getting stranded by Dan Galloway. (TV: Death to the Daleks)
