The first point to note about the Armada is that it was almost entirely a fleet of sailing-ships. The new period of naval war had begun. There had been hundreds of galleys at Lepanto, seventeen years earlier, but there were only four in the Armada, and none of these reached the Channel. The long, low, oar-driven warship, that for two thousand years had done so much fighting in the Mediterranean, proved useless in the long waves of the Atlantic.[7] The only oared ships that really took part in the campaign were the four galleasses, and in these the oar was only auxiliary to the spread of sail on their three full-rigged masts. The galleasse has been described in the story of Lepanto. It was an intermediate or transition type of ship. It seems to have so impressed the English onlookers that the four galleasses are given quite an unmerited importance in some of the popular narratives of the war. [7] Galleys were used in the land-locked Mediterranean and Baltic up to the first years of the nineteenth century, but the only sailors who ever ventured to take galleys into the wild weather of the Atlantic were the Norse Vikings. But the day of sails had come, and the really effective strength of the Armada lay in the tall galleons of the six "armadas" or squadrons of Portugal, the Spanish provinces, and the Levantine traders. The galleon was a large sailing-ship, but even as to the size of the galleons the popular tradition of history is full of exaggeration. Built primarily for commerce, not for war, they carried fewer guns than the galleasses, though many of them were of heavier tonnage. In those days every large trader carried a certain number of guns for her protection, but such guns were mostly of small calibre and short range.
