The 3rd Victim:

From the 1987 adaptation of Desyat Negrityat (Russian version
"And Then There Were None")



The last conversation MacArthur has with Vera where he
tells her that no one will leave the island alive.
Description:
General MacArthur revealed himself as retired World War I hero who has since aged drastically alone. He also frequently mentions his wife Leslie in flashbacks.

Accused of:
During the accusations, he's accused of deliberately sending Arthur Richmond(his wife's lover) to a mission where it was practically guaranteed that he wouldn't make it back alive.

Death by:
After he's accused, he feels extremely guilty and with Marston and Mrs.Roger's death he realizes no one will leave the island alive. He confesses to his crime revealing that he had found out about his wife's lover because she had accidentally switched the letters when she wrote to both of them at the same time. In the end, he sits by the sea alone waiting for his death to come.   

"Eight little Soldier boys travelling in Devon;
One said he'd stay there and then there were seven."  

Wargrave's Confession:
Wargrave's letter reveals that it was quite easy to kill MacArthur by bludgeoning him because the General was unaware, isolated, and defenseless. And also that all along he had been waiting for his "destiny."
