The annexed tables (pp. [315], [316]) give some details of Russian and Japanese armoured ships.

With regard to the armour it must be kept in mind for purposes of comparison that the armoured belts of the newer ships, nine inches at the thickest part, were of Harveyized or Krupp steel, and could resist penetration better than the thicker belts of the older ships. It will be noticed that the Japanese carried fewer of the heavier types of guns, but had more 6-inch quick-firers than the Russians. This is a point to bear in mind in following the story of the battle. It was the steady rain of 100-pounder shells from the quick-firers that paralysed the fighting power of the Russian ships.

Far more important than the mere number of guns was the fact that the Japanese shot straighter and had a more effective projectile. There was such a marked difference between the effect of the Japanese shells at Tsu-shima and in the naval battle of 10 August, 1904, that Captain Semenoff, who was present at both battles, thought that in the interval the Japanese must have adopted a more powerful kind of high explosive for their bursting charges. This was not the case. Throughout the war the Japanese used for their bursting charges the famous Chimose powder. But perhaps between 10 August, 1904, and the following May they had improved their fuses, so as to detonate the charge more certainly and thoroughly.

The first five battleships on the Russian list were up-to-date modern vessels. The "Navarin" was fairly fit to lie in line with them. The rest were, to use a familiar expression, "a scratch lot," coast-defence ships of small speed and old craft quite out of date. The decks of the larger ships were encumbered with an extra supply of coal, and this must have seriously diminished their margin of stability, with, as we shall see, disastrous results.

Admiral Togo could oppose to them only four modern battleships. But his two heavy cruisers, the "Nisshin" and "Kasuga" (the ships bought from Argentina on the eve of the war), might almost have been classed as smaller battleships, and certainly would have been given that rank a few years earlier. His fine fleet of armoured cruisers were at least a match for the Russian coast-defence ships and the older battleships.

Besides his armoured ships, Admiral Rojdestvensky had a squadron of six protected cruisers under Rear-Admiral Enquist, whose flag flew in the "Oleg," a vessel of 6750 tons launched in 1903, and completed next year. She had for her principal armament twelve six-inch quick-firers. The other cruisers were the "Aurora," of a little over 6000 tons, the "Svietlana," of nearly 4000, the "Jemschug," and "Izumrud," of 3000 tons (these two armed with 47 quick-firing guns), and the "Almaz," of 3285, a "scout" of good speed, carrying nothing heavier than 12-pounders. There was one auxiliary cruiser, the "Ural,"[26] a flotilla of nine destroyers, four transports, two repairing ships, and two hospital steamers.
