I am trying to piece together a world where a country has two territories. One territory is very far away from the other. Between the disjoined lands are long stretches of hostile enemy territory. Having distant territories is hardly a novel affair; the Romans, Persians and Ottomans boasted vast ones. However unlike many of such empires, the country in my world does not have a continuous slew of land. For a real world historical analog, we can look at the former state of East Pakistan:
It is clear from the map that the territories would face numerous logistic and strategic complications. East Pakistan was almost 2000 miles away from West Pakistan, and it stands to reason that this geographic dimension added to the cultural and political turmoil that ultimately drove East and West Pakistan apart during the Bangladesh Liberation War.
East Pakistan is certainly a decent starting point, but is by no means the best case scenario for a distantly disjoined country. One could arguably assert that the military presence West Pakistan had in East Pakistan ultimately worked against them. Allegations of genocide along with other complications led to the demise of East Pakistan in less than 20 years. I would like my world's disjoined state to last much longer.
Question: What is a viable military strategy for a disjoined state to secure sovereignty in the long run?
- Terminology: I will refer to the larger, main territory simply as "the state." While I will refer to the far flung territory as "the isolated territory"
- Of course the state is larger and stronger, the isolated territory is smaller and weaker but not a pushover. The isolated territory has enough supplies and troops for the short-term, but will not survive prolonged warfare or lengthy attrition
- The isolated territory is able to be self-sufficient in terms of sustenance, but it is landlocked and faces logistical challenges
- Rivers from the isolated territory reach the sea.
- Between the state and the isolated territory are roughly 2,000 miles of hostile enemy territory (depending on route)
- There are a total of 3 neighboring states, all of which are hostile
- Military strength is roughly equal between all 4 states
- Diplomacy has failed, alliances could not be forged, deals could not be struck
- The isolated territory's narrative is largely out of scope, but you may assume it's existence is rather new
- The loyalty of the isolated territory to the state is absolute. However, slight cultural differences exist.
- Era: Roughly middle ages (knights on horseback and the like)
Here are maps: [White = disjoined country] all other colors are hostile.
