[001] because of the incumbrance of the prior's predecessor. Thus it appears that whether a [002] feoffee who is mesne is a wrongful detainor or has enfeoffed others thereof and so incumbered [003] the tenement, whether he himself is impleaded by the assise or is vouched [004] to warranty by his tenant on his own deed,1 that his own feoffor will not be bound to [005] warrant, though he is bound [to warrant him] against strangers2 who had right in the [006] property before his feoffment.3 In that case the warranty binds from the last feoffee [007] to the first feoffor, and each feoffor is bound to warrant his own feoffee in order, [when [008] they have been enfeoffed to themselves and their heirs; if to themselves and their [009] heirs or to whom they wish to give or assign, the assignee or donee will then have his [010] choice of vouching his own feoffor to warranty or the feoffor of his feoffor directly, [011] because of the modus of the first gift. Thus it is necessary to consider whether one has [012] been enfeoffed in the one way or the other.] Suppose that A. first enfeoffs B. and B. [013] dies leaving an heir within age; A. takes the inheritance into his hand by reason of [014] wardship and enfeoffs C., who dies seised thereof leaving an heir within age, and A. [015] again takes the land into his hand by reason of wardship. When either of the heirs [016] brings an assise of mortdancestor against A. he cannot vouch a warrantor, because of [017] his own act and his own incumbrance, but let the assise [of the heir] of the last feoffee [018] proceed first; when he has recovered the assise brought against A. by the first feoffee's [019] [heir] then falls and will begin again against the [heir of the] last feoffee, that he may [020] vouch A. to warranty; and when the heir of the first feoffee recovers against A., let the [021] heir of the last feoffee have [escambium] to the value from the warrantor's land.4 What [022] is said of one feoffee must be observed in the case of several feoffees and their heirs ad [023] infinitum, as where A. enfeoffs B., B. C., C. D., D. E., and so ad infinitum. If one of the [024] chief lords, up to the first feoffor, [obtains possession of the land] lawfully, as by gift [025] or in the name of wardship or through any other lawful cause, or wrongfully, as by [026] intrusion of disseisin, whether he holds the tenement in his own hand and is impleaded [027] thereof, or enfeoffs others collaterally, one or several, together or successively, and is [028] vouched to warranty,
