Richard Cœur de Lion's return trip

This follows on from new maps posted on history & newmaps.

 Medievalist.net posted here a rethink of the circumstances of Lionheart's return from the Third Crusade, summary here and in three-sentences:

The article presents Attila Bárány’s argument that Richard I’s capture after the Third Crusade was primarily a product of high politics, not an accident of storms, pride, or divine punishment. Richard’s secretive, indirect route home and his decision to pass through risky territories are treated as calculated responses to the political threats posed by figures like Philip Augustus and Emperor Henry VI, who could profit from his detention. Leopold V’s personal resentment is seen as a catalyst rather than a sufficient cause, with Richard’s captivity and ransom functioning as tools of imperial strategy and diplomatic theatre.

Not only is it for me the third in a row of Hungarian writers: Bárány after Krasznahorkay and Szalay  prompted a last post in my other blog; but also Perplexity AI helped me flesh out the route specified in that paper.  Here are the data posted in a similar manner to previous maps of Japanese in Europe here.

The 12th. c. countries are from @harvard_CGA "DARMC Medieval World" here. The cities are all from the article. Those in brackets are interpolated using Perplexity AI in context (see bottom). The route is simple geometry between the points. The maritime portion is blanked out and filled as follows.

The sea route is from @vgagis "Medieval Sea routes in Europe during the Black Death" here - note the addendum on Black Death at the bottom here - it's not Lionheart's route, but an approximation as: 

Richard left his large ship at Corfu, hiring two small galleys to slip north up the Adriatic while avoiding hostile Italian and French ports. These galleys were repeatedly hit by winter storms and his vessel was finally driven ashore near Aquileia on the northern Adriatic coast in early December 1192. From this landfall he abandoned the sea route and continued overland through Alpine and imperial territories toward Vienna, where he was captured shortly before Christmas 1192.
