The documents C and B may indeed be related to one another. So many invasions occurred. Another connection is that the soldiers abandoned their defense, which meant that they would not be able to repel the invaders.
There is a correlation because losing protection would make it harder for the soldiers to defeat the invaders if there were several invasions.
It's conceivable that Documents C and B are related because Document B claimed that because the soldiers were helpless and surrendered, fled and rendered their army hopeless, the adversaries would seize control and a populace invasion would fill the void. As a result, Document B serves as both a justification for Rome's demise and evidence in Document C, which also depicts the invasion.
The two documents are related to one another. They are related since they both involve the military. The reasons why the military disintegrated are discussed in document B. The invasion of Rome by the six tribes is discussed in document C. If the army hadn't disintegrated, the tribes wouldn't have been able to attack.
This is due to the fact that documents B and C describe Rome's decline as a result of the invaders. It is explained in document B how the troops weakened themselves, and it is shown in document C together with a map of the empires that invaded Rome. My proof is found in B, where it states, "But when, due to carelessness and sloth, round drills were abandoned. This proof demonstrates the soldiers' slackness. Rome's invasions are depicted in C with lines, names, and dates. This proof provided me with the solution.
Given that they both compare how Rome's army declined, Document C and Document B may be related to one another. I discovered this information by looking through Doc B's search results and then observing how many different nations had attacked Doc C. When these sources discuss how many different nations Rome's soldiers faced without armor, they are compared.
