Key Takeaways

  • Campaign logistics: Julian assembled 65,000-90,000 troops and 1,000 supply ships for his Persian invasion, but burned the entire fleet when forced to retreat, leaving his army without provisions in hostile territory.
  • Strategic failure: Julian rejected reasonable peace terms from Persian King Shapur II because victory itself was his goal, not any coherent strategic objective like territorial gain or regime change, leaving no backup plan when Ctesiphon proved unassailable.
  • Defensive innovation: Cities that once surrendered to Roman armies on sight now featured advanced fortifications by 363 CE, making traditional siege tactics obsolete and forcing commanders to recalculate time, resources, and risk for urban assaults.
  • Leadership vulnerability: Julian fought without his breastplate during a multi-front Persian assault, took a spear to the liver, and died without naming a successor, demonstrating how personal courage without tactical caution creates succession crises.

That's rubrik.com. Hello, and welcome to the history of Rome. Episode one forty six, the Spear of Destiny. Last week, we covered the wide range of reforms Julian initiated after becoming emperor. Though he is usually remembered as the man who tried to stem the tide of Christianity, we should not forget that he was interested in more than just religion. And given enough time, it is possible that we could have been sitting here talking about Julian as a major transformative figure. But instead, we talk about him merely as a brief detour, an accidental left turn noticed and corrected within a block of the mistake. This week, we will get into why Julian's imperial course correction never got the empire further down his pagan Principate side road. In the end, it wasn't because of institutional barriers, entrenched interests, or even the irresistible destiny of Christianity. It was because of a forgotten breastplate and an anonymously thrown spear. After a frustrating winter spent butting heads with the citizens of Antioch, Julian was eager to leave behind the aggravating belligerency of his fellow citizens and focus his attention on a much easier enemy to grapple with, the saxonids. He didn't have to worry about placating the saxonids or making friends with the saxonids or even caring what the saxonids thought about his reform agenda. He just needed to beat the crap out of the saxonids. I imagine that as much as Julian was looking forward to the political bounce he would get from a successful campaign in the East, that he was also looking forward to the cathartic relief he would get from a good hard fight. Much to Julian's consternation, however, the Sassanids were presently trying to duck that fight. The Persian King Shapur the second spent most of his epic reign, which was an amazing seventy years long, vacillating between aggression and pacifism towards Rome. And it appears that with the death of his old enemy Constantius the second, that the king was ready to once again enter one of his passive phases. His recent victories, which had included the sack of a meetup, had turned out to have been of the pyrrhic variety. That is, the cost of the campaign far outweighed the benefit. Further fighting at this point would probably only shift the border between Rome and Persia a few yards in either direction. So what was the point? Shapur reached out to Julian and tried to work out a peace agreement that would satisfy both leaders. But Julian was not having it. He had come east to make war on the Sassanids, not to make peace with …
