The Princess and the Queen (mentioned)
Alan supported Queen Rhaenyra Targaryen and the blacks. Joined by Lord Owen Costayne and Ser Alan Beesbury, Lord Tarly trapped Lord Ormund Hightower's forces along the banks of the Honeywine between them and another army of blacks led by Lord Thaddeus Rowan and Tom Flowers. Ormund's lines started to crumble and defeat seemed all but a forgone conclusion. However, Prince Daeron Targaryen attacked on his dragon, Tessarion, turning the battle for the greens. Alan was captured after the Battle on the Honeywine.
