Wisconsin’s military history is one of service and sacrifice.

An examination of the Blue Book reveals how many Wisconsin residents served during the nation’s wars and other periods of hostilities, and how many were killed.

The numbers deserve a closer look as Veterans Day approaches. They also need some explanation. They are not a count of everyone who has ever worn the uniform, and they do not tell us how many Wisconsinites are deployed today.

Some volunteered. Others were drafted. Some lied about their age in order to be deployed. Some served to avoid punishment, others to continue a family legacy in the military. All served.

Civil War

We know of 91,379 Wisconsin soldiers in the Civil War. That includes some who enlisted more than once. The number of individual soldiers recruited in Wisconsin was about 80,000.

Records indicate 12,216 killed, the largest toll of any conflict it lists.

Spanish-American War

Wisconsin’s service count was 5,469, 134 killed, but that figure covers only the 1st, 2nd, 3rd and 4th Wisconsin regiments. Details were not available for Wisconsin residents who served in federal units.

That missing information matters. The figure is not a complete statewide death count.

Mexican border service

The Blue Book lists another 4,168 Wisconsin residents under Mexican Border Service. It does not provide a death count.

World War I

The state lists 122,215 Wisconsin residents who served and 3,932 killed in action.

World War II

History records 332,200 Wisconsin residents who served, more than in any other conflict. 8,390 were killed in action.

Korean War

Approximately 132,000 Wisconsin residents served during the Korean conflict and 729 killed.

These are wartime service figures. They should not be read as saying that all 132,000 served in Korea itself.

Vietnam

The Blue Book lists 165,400 who served and 1,239 killed. As with the Korean figure, the service count should not be treated as the number who served inside the country.

Lebanon, Grenada, Panama and other operations

Some Military service can get lost between the larger wars:

  • Lebanon and Grenada: 400 served, one killed.
  • Panama: 520 served, one killed.
  • Somalia: 426 served, two killed.
  • Bosnia and Kosovo: 678 served. A death count was not available.

A missing figure does not mean zero.

Desert Shield and Desert Storm

More than10,400 Wisconsin residents who served in Operations Desert Shield and Desert Storm, with 11 killed.

Since Sept. 11, 2001

The table records 36,941 military and civilian personnel deployed from Wisconsin since Sept. 11, 2001. That is not an up-to-date deployment count. It runs only through December 2018, when the Defense Department stopped reporting deployments by state, according to the Blue Book’s footnote.

The table lists 128 killed, including one person killed in the attack on the Pentagon on Sept. 11, 2001. The service table cites departmental data from April 2021. That figure should not be presented as a death toll updated through 2026.

What the table leaves out

The listed figures in the death column add up to 26,783. That is a sum of the entries, not a complete, current accounting of Wisconsin’s military deaths. Some entries are incomplete, some are unavailable, and the post-Sept. 11 figures have the limits described above.

Nor should the service column be added up and presented as a count of individual veterans. The Civil War entry includes repeat enlistments, and someone could have served during more than one conflict.

The Blue Book says the table covers Wisconsin residents who served on active duty during declared wars and officially designated periods of hostilities. It is not a roster of everyone who served in peacetime.

Wisconsin veterans today

The Census Bureau’s QuickFacts for Wisconsin estimates the state’s veteran population at 288,078, based on American Community Survey data collected from 2020 through 2024. That is a multiyear survey estimate, not a live count for November 2026.

It measures something different from the historical service table: veterans living in Wisconsin, including those whose service was outside the wartime periods listed above.

Their service counts, too. So does the service of those whose names and experiences cannot be captured in a statewide table.

Veterans Day is a good time to thank them.
