The Confederate loss is not reported. They left on the field, to be cared for by their adversary, 21 of their dead and 35 of their wounded. Among these were Gray, Vincent, and Reily.
Taylor gives the number of his infantry engaged in the charge on Birge's right as less than 1,000. The disparity of the opposing forces in that affair was, therefore, not important, and Birge's somewhat greater numbers may fairly be considered as off-set by the advantages of Taylor's position and the familiarity with the country common to nearly all the Confederate soldiers there engaged, while to their antagonists it was an unknown land. Grover's whole force was about 5,000, of all arms, but of these, though all are to be taken into account, nearly a third were in reserve, neither firing nor under fire, while another third met a resistance so light that its loss was no more than one per cent. of its numbers --hardly more than it had suffered in the skirmishes of the day before. Grover had eighteen pieces of artillery, of which but four were in action; Taylor also had four guns of which he made good use, and these, toward the close of the battle, were reinforced by the five heavy guns of the _Diana_, of which, however, it is probable that but one, or at most two, could be brought to bear.
The field of battle was so contracted that Taylor's strength sufficed to occupy its front, while Grover was hindered or prevented from deploying a force large enough to outflank and crush his antagonist at a blow.
Viewed from a Confederate standpoint, the issue forms an instructive example of the great results that may be achieved by a right use of small forces. If, on the other hand, one turns to consider the lost opportunity of Grover, two things stand out in strong relief: the one, the positive disadvantage of employing forces, too large for the affair in hand or for the scene of operations; the other, that bold adventures must be carried boldly to the end.
Instead of making the campaign with four brigades and twenty-four guns, as Weitzel's original plan had contemplated, Banks, for greater security, set out with seven brigades and fifty-six guns. So far as concerned the main body ascending the Teche, this excess of strength could do no harm, but it was otherwise with the turning column by the lake; for to the needless augmentation of the artillery were directly due not only the day and night first lost, but also the still more precious hours of daylight consumed in landing guns that were not to fire a shot. Two brigades of infantry, with six guns at most, landing at Indian Bend, and marching directly toward the Cypremort, and quickly entrenching across both roads at or near their upper fork, would have been enough to hold the position against the best efforts of the whole of Taylor's army, with Emory close on their heels; and thus Taylor must have been lost and the war in Western Louisiana brought to an end. Consequences many and far-reaching would have followed. Moreover, when it was determined to use more than two divisions one of these was naturally Grover's, and thus it happened that to Grover, who knew nothing of the country, was assigned the delicate duty first cut out for Weitzel, while Weitzel, who had studied to the last point every detail of the topography and of the plan, stayed behind as the third in command of the column destined to butt its nose against the breastworks of Bisland and wait for the real work to be done a day's march on their farther side.
