The Report of Philip de Thame, prior of the English province, was submitted in 1338 to Grand Master Elyan de Villanova (Helion de Villeneuve), who was resident at the Order's headquarters in Rhodes. Today it is housed, appropriately, on the island of Malta, the home of the headquarters of the Order of St John from 1530 until the end of the eighteenth century. The purpose of the Report was to provide an extent of all the Hospitaller property in England, including that which had belonged to the Templars. All property was recorded: that which had initially been donated to the Hospitallers, and that which had been transferred to them following the suppression of the Templars in 1312. In addition, the Report listed property which had belonged to the Templars, was known not to have been transferred to the Hospitallers, and to which the Order laid claim.

In a sense, the Report was a statement of progress in the convoluted process of reclaiming the former Templar properties, which would have been of critical interest to both Philip de Thame and Elyan de Villanova. The Report differs from the accounts of 1308–13 in a number of respects. It does not give an inventory of deadstock, livestock or the content of granaries; neither does it itemise crop acreage or agricultural personnel, all of which were recorded in considerable detail in the accounts of 1308–13. After a brief description of the format of the Report, this chapter analyses the Lincolnshire content and compares the data relating to property and personnel with that in the accounts of 1308–13. In addition, a comparison is made between the former Templar properties accounted in 1308 and those recorded in the Report of 1338. This establishes the extent to which Templar properties had been transferred to the Hospitallers in Lincolnshire during the intervening years, and the degree to which the Report was comprehensive. The transcription of the Report was completed by Lambert Blackwell Larking, and is accompanied by an introduction by John Mitchell Kemble. The work was first published by the Camden Society in 1857. This remains the sole survey exclusive to the Hospitaller estates in England.

It can hardly be coincidental that de Thame's Report was made the year after the outbreak of the Hundred Years War with France, in 1337.
