Modern historians consider Chalkokondyles' account as being closer to the truth, envisioning a drama where David weighed these two choices. The walls of Trebizond were massive and elaborate; David expected his relative Hassan Uzun to arrive at any moment to relieve the siege, or perhaps his ally the King of Georgia, or perhaps even both. Meanwhile, George Amiroutzes was at this side, allegedly suborned by his cousin to betray David, advising his emperor that surrender would be the prudent course, and reminding him what happened to Constantinople because Constantine refused Mehmed's offer; perhaps Amiroutzes even showed David letters from Sara Khatun informing him that no help would be forthcoming from that quarter.[39]
