Mishnayos Bava Kamma Perek 10 Mishnah 5

In a case of one who robs a field from an-other and thugs [massikin] subsequently take the field from the robber, the halakha is dependent upon the circumstances: If it is a regional disaster in which the thugs seize all the property in the region, the robber says to the owner of the field: That which is yours is before you, i.e., it is your prerogative to try to reclaim it from the thugs. No compensation is required since the thugs would have seized the property in any event. But if the thugs took that field alone due to the robber, the robber is obligated to provide the owner with a different field. If a river flooded a misappropriated field, the robber may say to its owner: That which is yours is before you, and no compensation is required. Since the field would have been flooded in any case, the robber has not caused the damage to the field, and is therefore exempt.
