Answer: Hamish and Stephen
"In the year of our Lord 1314, patriots of Scotland, starving and outnumbered, chargedd the fields of Bannockburn. They fought like warrior poets. They fought like Scotsmen. And won their freedom. Forever".
William Wallace has just been executed - disemboweled, drawn and quartered, and beheaded. Just crowned as the King of Scotland, Robert the Bruce, with his ragtag army, is preparing to pay homage to the English army, and in return gain the English endorsement of his rule. Robert looks at the handkerchief Murron made for William that he has kept. Instead, he rallies the men, and leads them into battle.
Hamish, Campbell, and Morrison were fictional people; there is one legend that Wallace had a friend named Stephen of Ireland, and another that Wallace's closest friend was named Kerly. Robert the Bruce was crowned King of Scotland in 1306, but never assembled his men to accept endorsement from anyone. The Battle of Bannockburn began as the Scots were laying siege to Stirling Castle, which was held by the English at the time. While trying to lift the siege, an English army was defeated by a much smaller Scottish army led by Robert the Bruce.
