A determination is made of the nonlinear evolution of a reconnecting magnetic field configuration similar to that occurring just before the onset of 'post'-flare loops in two-ribbon flares. The evolution, which is obtained by numerically solving the resistive MHD equations, reveals two new features that have not yet been incorporated into contemporary models of 'post'-flare loops. One is the formation of a nearly stationary fast-mode shock above the region corresponding to the top of the loops. This fast-mode shock occurs immediately below the magnetic neutral line and between the slow-mode shocks associated with fast magnetic reconnection at the neutral line. The other new feature is the creation and annihilation of large-scale magnetic islands in the current sheet above the loops. The annihilation of the islands occurs very rapidly and is seen as a manifestation of the coalescence instability. It is believed that the creation and annihilation of magnetic islands may be important in understanding the energetics of 'post'-flare loops since the coalescence instability can produce an intermittent energy release more than an order of magnitude faster than that predicted by steady-state reconnection theories.
