Converts refuse to take up arms to defend themselves

Alma 24 (http://scriptures.lds.org/en/alma/24) describes how when the
Lamanites were converted to the gospel of Jesus Christ, they buried
their weapons and covenanted to not go to battle again.  When they
were attacked, rather than defend themselves, they lay down in front
of their enemies.  Many were killed but many more of their enemies
were converted and joined them.

 26 And it came to pass that the people of God were joined that day by
more than the number who had been slain; and those who had been slain
were righteous people, therefore we have no reason to doubt but what
they were saved.
 27 And there was not a wicked man slain among them; but there were
more than a thousand brought to the knowledge of the truth; thus we
see that the Lord worketh in many ways to the salvation of his people.
