The charges of the twisted D-branes of certain WZW models are determined. Thetwisted D-branes are labelled by twisted representations of the affine algebra,and their charge is simply the ground state multiplicity of the twistedrepresentation. It is shown that the resulting charge group is isomorphic tothe charge group of the untwisted branes, as had been anticipated from aK-theory calculation. Our arguments rely on a number of non-trivial Lietheoretic identities.Comment: 27 pages, 1 figure, harvmac (b
