Answer:
As you know, Roanoke was when John White went to get supplies when he was starting a new island by himself... What happened was He brought some people do an island to start new lives, but they ran out of supplies when he was building so he went back to Europe to get supplies, but little did he know that Europe was at war so John White had to fight Galaxy told the people in his Island that he would be gone for like maybe 2 months he was gone for a year when the war was finally over he went back to the island and then he found everyone gone, even all the houses and people without any trace it looked like they weren't even like there the only thing that was left was a carving into the tree which said "Roanoke" So, a failure could have been that John White was there for a year because if he just went back for a few months the people probably would have been there because he left them with only a little bit of food so if he left them with more food and supplies because he was a little bit selfish and he brought a bunch of supplies and food on the sleep with him as he went back so if he wasn't at Europe for so long and he left them with more supplies this whole disaster could have probably been avoided better.
