Thus far, I may repeat, I have corrected James solely by the evidence of his own side; now I shall bring in some American authorities. These do not contradict the British official letters, for they virtually agree with them; but they do go against James' unsupported assertions, and, being made by naval officers of irreproachable reputation, will certainly outweigh them. In the first place, James asserts that on the main-deck of the Confiance but 13 guns were presented in broadside, two 32-pound carronades being thrust through the bridle- and two others through the stern-ports; so he excludes two of her guns from the broadside. Such guns would have been of great use to her at certain stages of the combat, and ought to be included in the force. But besides this the American officers positively say that she had a broadside of 15 guns. Adding these two guns, and making a trifling change in the arrangement of the guns in the row-galleys, we get a broadside of 1,192 lbs., exactly as I have given it above. There is no difficulty in accounting for the difference of tonnage as given by James and by the Americans, for we have considered the same subject in reference to the battle of Lake Erie. James calculates the American tonnage as if for sea-vessels of deep holds, while, as regards the British vessels, he allows for the shallow holds that all the lake craft had; that is, he gives in one the nominal, in the other the real, tonnage. This fully accounts for the discrepancy. It only remains to account for the difference in the number of men. From James we can get 772. In the first place, we can reason by analogy. I have already shown that, as regards the battle of Lake Erie, he is convicted (by English, not by American, evidence) of having underestimated Barclay's force by about 25 per cent. If he did the same thing here, the British force was over 1,000 strong, and I have no doubt that it was. But we have other proofs. On p. 417 of the "Naval Occurrences" he says the complement of the four captured British vessels amounted to 420 men, of whom 54 were killed in action, leaving 366 prisoners, including the wounded. But the report of prisoners, as given by the American authorities, gives 369 officers and seamen unhurt or but slightly wounded, 57 wounded men paroled, and other wounded whose number was unspecified. Supposing this number to have been 82, and adding 54 dead, we would get in all 550 men for the four ships, the number I have adopted in my list. This would make the British wounded 129 instead of 116, as James says: but neither the Americans nor the British seem to have enumerated all their wounded in this fight. Taking into account all these considerations, it will be seen that the figures I have given are probably approximately correct, and, at any rate, indicate pretty closely the relative strength of the two squadrons. The slight differences in tonnage and crews (158 tons and 55 men, in favor of the British) are so trivial that they need not be taken into account, and we will merely consider the broadside force. In absolute weight of metal the two combatants were evenly matched—almost exactly;—but whereas from Downie's broadside of 1,192 lbs. 660 were from long and 532 from short guns, of Macdonough's broadside of 1,194 lbs., but 480 were from long and 714 from short pieces. The forces were thus equal, except that Downie opposed 180 lbs. from long guns to 182 from carronades; as if 10 long 18's were opposed to ten 18-pound carronades. This would make the odds on their face about 10 to 9 against the Americans; in reality they were greater, for the possession of the Confiance was a very great advantage. The action is, as regards metal, the exact reverse of those between Chauncy and Yeo. Take, for example, the fight off Burlington on Sept. 28, 1813. Yeo's broadside was 1,374 lbs. to Chauncy's 1,288; but whereas only 180 of Yeo's was from long guns, of Chauncy's but 536 was from carronades. Chauncy's fleet was thus much the superior. At least we must say this: if Macdonough beat merely an equal force, then Yeo made a most disgraceful and cowardly flight before an inferior foe; but if we contend that Macdonough's force was inferior to that of his antagonist, then we must admit that Yeo's was in like manner inferior to Chauncy's. These rules work both ways. The Confiance was a heavier vessel than the Pike, presenting in broadside one long 24- and three 32-pound carronades more than the latter. James (vol. vi, p. 355) says: "The Pike alone was nearly a match for Sir James Yeo's squadron," and Brenton says (vol. ii, 503): "The General Pike was more than a match for the whole British squadron." Neither of these writers means quite as much as he says, for the logical result would be that the Confiance alone was a match for all of Macdonough's force. Still it is safe to say that the Pike gave Chauncy a great advantage, and that the Confiance made Downie's fleet much superior to Macdonough's.
Macdonough saw that the British would be forced to make the attack in order to get the control of the waters. On this long, narrow lake the winds usually blow pretty nearly north or south, and the set of the current is of course northward; all the vessels, being flat and shallow, could not beat to windward well, so there was little chance of the British making the attack when there was a southerly wind blowing. So late in the season there was danger of sudden and furious gales, which would make it risky for Downie to wait outside the bay till the wind suited him; and inside the bay the wind was pretty sure to be light and baffling. Young Macdonough (then but 28 years of age) calculated all these chances very coolly and decided to await the attack at anchor in Plattsburg Bay, with the head of his line so far to the north that it could hardly be turned; and then proceeded to make all the other preparations with the same foresight. Not only were his vessels provided with springs, but also with anchors to be used astern in any emergency. The Saratoga was further prepared for a change of wind, or for the necessity of winding ship, by having a kedge planted broad off on each of her bows, with a hawser and preventer hawser (hanging in bights under water) leading from each quarter to the kedge on that side. There had not been time to train the men thoroughly at the guns; and to make these produce their full effect the constant supervision of the officers had to be exerted. The British were laboring under this same disadvantage, but neither side felt the want very much, as the smooth water, stationary position of the ships, and fair range, made the fire of both sides very destructive.
Plattsburg Bay is deep and opens to the southward; so that a wind which would enable the British to sail up the lake would force them to beat when entering the bay. The east side of the mouth of the bay is formed by Cumberland Head; the entrance is about a mile and a half across, and the other boundary, southwest from the Head, is an extensive shoal, and a small, low island. This is called Crab Island, and on it was a hospital and one six-pounder gun, which was to be manned in case of necessity by the strongest patients. Macdonough had anchored in a north-and-south line a little to the south of the outlet of the Saranac, and out of range of the shore batteries, being two miles from the western shore. The head of his line was so near Cumberland Head that an attempt to turn it would place the opponent under a very heavy fire, while to the south the shoal prevented a flank attack. The Eagle lay to the north, flanked on each side by a couple of gun-boats; then came the Saratoga, with three gun-boats between her and the Ticonderoga, the next in line; then came three gun-boats and the Preble.
