"The Delaware Army National Guard traces its origins back to August 31, 1655, when Swedish settlers were asked to take up arms to defend the colony against a Dutch attack on Fort Christina.

During the American Revolution, Delaware's First Regiment fought with General George Washington at the Battle of Long Island.

In the War of 1812 all Delaware volunteer units saw service at Lewes, where they comprised the bulk of force that drove off a British naval squadron seeking control of the Delaware River. The 198th Signal Battalion (ARNG DE), which traces its lineage to three militia units that were federalized during the War of 1812, is one of only nineteen Army National Guard units with campaign credit for the War of 1812."
