The fate of the gas in a merging subcluster is discussed on the basis of Rosat X-ray images of the cluster A2256. It is shown that it may not be shocked during the merger; specifically, if either cluster or subcluster contains a cooling flow, the cooling gas will not necessarily be heated but can thermalize its bulk kinetic energy in the less dense hot gas. As clusters evolve via hierarchical mergers, cooling flows are interrupted as the intracluster medium is stirred up but are then quickly reestablished. It is shown that the subcluster has a cooling flow. The X-ray subcluster in A2256 coincides with a diffuse radio source and is close to several head-tail radio sources. It is suggested that these sources were originally members of the subcluster and that ram-pressure stripping of the surrounding subcluster core has created the diffuse radio source from their lobes.
