The Skyrme model in \(2+1\) dimensions, expressed as an \(O(4) \sigma\)-model, is augmented by the addition of a symmetry-breaking potential and has both instanton and sphaleron solutions. In order to obtain an explicit sphaleron configuration, the quadratic kinetic term is dropped and the stability
