On this date in 1304, Stirling Castle fell to the forces of King Edward I of England, who had laid siege to the castle in April of that year.  Stirling Castle was the last holdout in Edward’s effort to gain control of Scotland, in a six-year effort that began with his defeat of William Wallace during the battle of Falkirk in 1298.  Unable to achieve surrender of the castle, Edward had commissioned his chief engineer, Master James of St. George, to design and build what is believed to be the largest trebuchet ever, which was named Lupus Guerre (or War Wolf in English).  The massive siege engine required 30 wagons to transport when disassembled and was estimated to measure between 300 and 400 feet in length (that is, at least the length of an American football field, perhaps as much as 1/3 longer).  It took five master carpenters and 49 laborers three months to build.  It was capable of accurately hurling missiles that weighed up to 300 pounds.

The castle’s governor, William Oliphant, surrendered on this date in 1304 and was imprisoned in the Tower of London.  He ultimately switched sides in the War of Scottish Independence, supporting the English, along with most of the rest of Scotland, William Wallace being the exception. In 1309, Oliphant was back at Stirling Castle, now in service to King Edward II of England.  In 1312, he was captured by the forces of Robert the Bruce, King of Scots, and sent into exile to the western isles, where he is believed to have died as a Scottish prisoner.

I could find no public domain poetry related to the Siege of Stirling Castle in 1304 nor to War Wolf.
