What are the dimensions of garrison flags used during the War of 1812?

The dimensions of garrison flags used during the War of 1812 were 20 feet by 40 feet. Garrison flags were large flags that were typically flown over military installations and represented the strength and presence of the U.S. military at that time. Their size was symbolic, making them visible from a distance and instilling a sense of pride and patriotism among the troops and the local populace.

The other options do not align with the historical specifications of garrison flags during this period. The 30 feet by 42 feet option is larger than the standard garrison flag dimensions. The 15 feet by 25 feet option and the 10 feet by 15 feet option are both smaller than what was traditionally used for garrison flags in the War of 1812, which further highlights the significance of the larger size in military displays. Therefore, the 20 feet by 40 feet dimensions accurately reflect the design and purpose of garrison flags from that era.
