Here we have the accidental loss of the definite article the in the 1906 LDS edition. This omission of the the reverses the meaning. The remainder of the men were definitely not “in charge of Lehi and Teancum”. The definite article the is required here and will be maintained.
Summary: Maintain in Alma 61:15 the definite article the in the phrase “in the charge of Lehi and Teancum”.
