Alma 56:33

And it came to pass that Antipus did march forth, with a part of his army, leaving the remainder to maintain the city. But he did not march forth, until I had gone forth with my little army, and came near the city Antiparah.

Antipus marched out with part of his army. He left some men to guard the city. But he didn’t march out until I had left with my little army and gotten near the city of Antiparah.

“Antipus marched out with part of his army, leaving the rest to defend the city. But he waited until I’d left with my small army and gotten close to Antiparah.”
