Helaman 1:25

But behold, this march of Coriantumr through the centre of the land, gave Moronihah great advantage over them, notwithstanding the greatness of the number of the Nephites which were slain;

But Coriantumr’s march through the middle of the land gave Moronihah a great advantage over them. This was true even though many Nephites were killed.

But Coriantumr’s bold march through the heart of the land actually gave Moronihah a huge advantage, despite all the Nephites who were killed.
