William Duane, A military dictionary
“ Some one column must determine the relative situation of the others, and divisions must be more closed up than in a march to a flank, and in proportion as they draw near to the enemy must exactness and attention increase. The general, in consequence of the observations he has made, will determine on his disposition: the columns which are now probably halted and collected will be subdivided and multiplied; each body will be directed on its point of formation, and the component parts of each will in due time disengage from the general column, and form in line. ”
