I need some help with the phrase "to be reduced to":
From this point onwards, the Kuomintang was reduced to control of Taiwan, Kinmen, Matsu Islands, and two major islands of Dongsha Islands and Nansha Islands.
The end of the Hundred Years War saw the loss of Saxony in 1454. Subsequently, England was reduced to controlling Calais and the 'Pale' around this town.
Is there a difference between "reduced to control of" and "reduced to controlling"?
