Cornelius, Cablava,
Of course the problem is knowing which account to use for the reconstruction, as they vary and are contradictory about some details. What is apparent from all of them is that the journey from Ternate to the point where they ran aground was anything but straightforward.
There are only five real sources of information: (1) The World Encompassed, not published until almost fifty years after the voyage and supposedly based on the notes of Francis Fletcher, Drake's preacher. (2) The "official" Hakluyt account first published about 1589, which was a composite of three main sources, with Fletcher's notes the likely source of that portion after leaving Mexico, (3 and 4) the two depositions made by Drake's cousin John after being captured by the Spanish a couple of years after the circumnavigation) and (5) the hand-written Anonymous Narrative account.
The conclusion that Drake ran aground on the Mulapatia reef, as earlier made by Corbet and Wagner and now suggested as a possibility by Cornelius, is consistent with the narrative and latitudes contained in the World Encompassed account, though the details are insufficient to draw a definite conclusion.
The Hakluyt account (not written by Francis Pretty, by the way, Cablava) does not contain sufficient detail to draw a conclusion.
Neither does the Anonymous Narrative, which was compiled by Hakluyt's assistant, Philip Jones, from the testimony of eight senior members of Drake's crew. It says that "shortly after they were departed hence (Ternate) they saw a small island covered with wood, whereof they throughly furnished their ship" This was the so-called island of crabs, and it then says that after leaving it "... keeping his course westerly till the eighth of January at night, the ran suddenly on a rock ..."
John Drake's first deposition provides information and latitudes that do not correspond with the WE, and text that gives some idea about the vagaries of Drake's movements after leaving Ternate. It says: "From thence (Ternate) they went to an island situated in four degrees north." This was the Island of Crabs, which the WE placed in almost two degrees south. Later, it says "after leaving the Island of Crabs, where they had left the negress and the negroes and which is situated in four degrees, they were driven by the wind out of their course, first in one direction and then in another for a whole month. One night they were caught by a very good south wind. Among some islands,in five or six degrees, the ship ran aground on a ledge of rock in such a way that from its poop they could not find bottom at a depth of more than three hundred fathoms ...." It also says that "from they went to an island named Java, which is in eight degrees"
This account would place the running aground much further south, around the southern tip of Celebes, and the latitude quoted for Java suggests that his information was reasonably accurate. The comment about moving in different directions for a month also shows how difficult it is to make assumptions about the path and progress of the Golden Hind during this phase of the voyage.
John Drake's second declaration is not as specific about latitudes, and contains somewhat different information about the movements: "After leaving Terrenate they sailed among many islands to one they named "of crabs" .... and sailing from there among many islands and shoals, their ship ran aground and remained thus for twenty hours. They lightened her of all that was not silver and she afterwards got afloat."
I do not think this second statement adds a great deal, and if anything the description would seem to me more reminiscent of the islands and shoals south of Peleng, although there are groups of island just south west and south of Celebes, in the latitude quoted in John Drake's first deposition.
Cornelius, that old chart you received was a wonderful gift, and must be a pleasure to have and to examine. I have no detailed maps of the area we are talking about in my collection, and I wonder if you have a chart that shows the Mulapatia Reef, and the depths of water on and immediately round it. I suspect that this was where Drake ran aground, though it would only be by finding the cannons that the case would be proved, I think.
This is an interesting problem, and if it was easy to solve, somebody would have done so a long time ago.
