the journal of the Society of Antiquaries of London, in 1773. Aided by the minister of the parish, the Reverend Buttonshaw, Colebooke enquired among elderly locals as to whether they knew of the oak tree mentioned by Harris, but none had. Colebrooke believed that the Britons had retreated to near Addington after their defeat at the fifth-century Battle of Aylesford, and that it was here that they buried their military leader, Categern. The later archaeologist John H. Evans described Colebrooke's descriptions and drawings as "almost completely worthless" because the antiquarian mistook the rectangular chambered tomb for a stone circle. Colebrook's analysis was echoed in the 18th-century writings of Samuel Pegge, Edward Hasted, and John Thorpe. In 1827, the road passing through the tomb was widened and deepened. To achieve this, workmen removed two of the sarsens from the revetment kerb and placed them in the corner of the wood to the south of the monument. In the early 1840s, the Reverend Beale Post conducted investigations into the Medway Megaliths, writing them up in a manuscript that was left unpublished; this included Addington Long Barrow and Chestnuts Long Barrow, which he collectively labelled the "Addington Circles". Thomas Wright recorded that in 1845 a local parson, the Reverend Lambert Blackwell Larking, dug into a chamber at Addington, discovering "fragments of rude pottery". From the context in which Wright wrote, it seems that Addington Long Barrow is referred to, although it remains possible that Chestnuts was the barrow in question. In the early 1860s, Charles Roach Smith visited the site alongside Charles Warne and Charles Moore Jessop, the latter of whom described it as a "Celtic" monument in a subsequent article for Gentleman's Magazine. In 1871, Edwin Dunkin published a basic plan of the monument, noting that there were similar chambered tombs around Britain. In 1880, the archaeologist Flinders Petrie included the Addington stones in his list of Kentish earthworks; he commented that "with extraordinary perversity [they] have been hitherto described as forming a circle, though they appear to be very plainly in two lines". He published a small, basic plan of the monument. The barrow then received a mention in George Payne's Collectanea Cantiana, published in 1893. Payne noted a folk tradition that stone avenues connected Coldrum to the Addington Long Barrow, although he commented that he was unable to discover any evidence of this feature. The earliest published photographs of the
