The Rhode Island National Guard traces it origins to the earliest known colonial defensive force which was formed on May 13, , and called the "Traine Band", in Portsmouth, Rhode Island. Each town had at least one militia company commanded by a captain or a lieutenant. In Cranston was promoted to major. In the town companies were organized into two regiments - the Regiment of the Islands i. Each regiment originally was commanded by a major and the two majors presumably reported directly to the governor. The 1st Regiment consisted of six companies and the 2nd Regiment had nine companies.
