Until the use of great ordnance had been sufficiently developed at sea to enable an enemy ship to be overcome at a distance, it is obvious that the dispute for the mastery could only be settled by hand-to-hand encounter. In these circumstances there would be no need of any method of indicating surrender other than by a personal appeal for quarter on the part of the vanquished crew, and indeed, the vanquished would hardly have the time or opportunity of removing the various flags placed along the bulwarks or flown from the masthead as a preliminary to such an appeal. But when it became possible for the ship to be destroyed from a distance, some method of indicating a wish to surrender on terms became necessary. This appears to have first been provided by displaying a flag of truce, a practice that was no doubt adopted about the beginning of the sixteenth century from the usages of land warfare where it had been current for many centuries. The following instance of its employment at sea occurred during Sir Richard Hawkins' voyage into the South Sea in 1593-4. In April, 1594, Hawkins' ship was caught at a disadvantage in the Bay of San Mateo. The crew were not over-anxious to fight, and talked of surrendering. Hawkins harangued them: "Came we into the South Sea," he asked, "to put out flagges of truce? And left we our pleasant England, with all her contentments with intention and purpose to avayle ourselves of white ragges?" After some fighting, which their neglect of proper preparations rendered useless, the captain of the ship "presently caused a flagge of truce to be put in place of our Ensigne, and began to parley of our surrendering[399]." It will be noted that the colours were hauled down and the white flag then hoisted on the ensign staff.
