The answer is A. the sinking of the Lusitania
I think is the Nullification crisis and the war he fought.
I am not writing the format of the letter or anything, but I will write a small para for u .
Dear (whoever),
We are safe here , hope everything is fine at home too . The crusades fight goes on from morning to evening . Hope everyone is healthy at home . Also convey my best of luck to my brother for his final test next month .
I am seeing a crusade war for the first time in my life . I am very scared but also feeling quite relieved that my elder brother is also there with me . He couldn’t write a letter to you as he is very busy here . In the was , a lot of bloodshed takes place and knives , swords and many other weapons are used . We will reach home back soon hopefully after the war . I wish we return victorious and we all can celebrate our victory at home .
Try giving a letter in reply soon . Waiting to hear from you , father and brother .
This is it , you can change anything if u want , any grammar mistakes then pls forgive ...
Hope this was helpful .
