The overall tone of the passage "Caius Julius Caesar, the first Roman that came into Britain" is that, Julius Caesar was proud and felt like he could conquer Britain and take it for his own. Hope this answers your question. Have a great day ahead!
you should start it with an opinion. for example : Romeo and Juliet was the most tragic love story in history. (or if you disagree) Romeo and Juliet was the most simpleminded story ever! after that you should use some evidents to back up your claim. basic reasons why you think what you think. I hope i helped <3 (writing is sumthin dats simple for me lemme kno if u need anymore help)
