core of a Greek expedition against the city of Troy, but few would argue that the Homeric poems faithfully represent the actual events of the war. In November 2001, geologist John C. Kraft and classicist John V. Luce presented the results of investigations into the geology of the region that had started in 1977. The geologists compared the present geology with the landscapes and coastal features described in the Iliad and other classical sources, notably Strabo's Geographica. Their conclusion was that there is regularly a consistency between the location of Troy as identified by Schliemann (and other locations such as the Greek camp), the geological evidence, and descriptions of the topography and accounts of the battle in the Iliad, although of course this could be a coincidence. In the twentieth century scholars have attempted to draw conclusions based on Hittite and Egyptian texts that date to the time of the Trojan War. While they give a general description of the political situation in the region at the time, their information on whether this particular conflict took place is limited. Andrew Dalby notes that while the Trojan War most likely did take place in some form and is therefore grounded in history, its true nature is unknown. The Tawagalawa letter mentions a kingdom of Ahhiyawa (Achaea, or Greece) that lies beyond the sea (that would be the Aegean) and controls Milliwanda, which is identified with Miletus. Also mentioned in this and other letters is the Assuwa confederation made of 22 cities and countries which included the city of Wilusa (Ilios or Ilium). The Milawata letter implies this city lies on the north of the Assuwa confederation, beyond the Seha river. While the identification of Wilusa with Ilium (that is, Troy) is always controversial, in the 1990s it gained majority acceptance. In the Alaksandu treaty (c. 1280 BC) the king of the city is named Alaksandu, and Paris's name in the Iliad (among other works) is Alexander. The Tawagalawa letter (dated c. 1250 BC) which is addressed to the king of Ahhiyawa actually says: "Now as we have come to an agreement on Wilusa over which we went to war ..." Formerly under the Hittites, the Assuwa confederation defected after the battle of Kadesh between Egypt and the Hittites (c. 1274 BC). In 1230 BC Hittite king Tudhaliya IV (c. 1240–1210 BC) campaigned against this federation. Under Arnuwanda III (c. 1210–1205 BC)
