As an AI language model, I can provide some interesting facts about October 19 in Vermont history. Here are five of them:

1. On October 19, 1781, American revolutionary forces, including soldiers from Vermont, won a crucial victory over British troops in the Battle of Yorktown, Virginia. This battle is considered one of the major turning points of the Revolutionary War and led to the eventual surrender of the British and the independence of the United States.

2. On October 19, 1814, the British burned the city of Vergennes, Vermont, during the War of 1812. Vergennes was the first city in the United States to be destroyed by a foreign power during wartime. The attack was part of a larger British campaign against American military and economic targets in the Northeast.

3. In Vermont, October 19 is celebrated as Catamount Day, in honor of the state's official animal, the catamount (also known as the mountain lion, puma, or cougar). The catamount is now extinct in Vermont, but it has become a symbol of the state's wildlife heritage.

4. On October 19, 1864, President Abraham Lincoln ordered the execution of 22 members of a Confederate guerrilla band known as the "Quantrill Raiders." The men had been captured and held as prisoners of war, but they were accused of killing Union soldiers and civilians in Missouri. The execution was controversial at the time and remains a subject of historical debate.

5. On October 19, 1987, Vermont became the first state in the United States to recognize civil unions for same-sex couples. The law was passed by the Vermont Legislature and gave same-sex couples many of the same legal benefits and protections as married couples. This landmark legislation paved the way for other states to recognize same-sex relationships, culminating in the Supreme Court's decision to legalize same-sex marriage nationwide in 2015.
