Battledetective.com started in 2007 out of the personal interest of Tom, the webmaster. From his parents, he inherited a fascination for World War Two in general and Operation Market Garden in particular. An exact date of when his enthusiasm started is difficult to determine, but there is evidence of Tom corresponding with renowned Dutch historian Dr. Lou de Jong of the Netherlands Royal Institute for War Documentation dating back to 1983. At age 13 Tom discovered an error in De Jong's authoritative 29-volume work "The Kingdom of the Netherlands in World War Two" and wrote the author about his findings.

Wrong caption

The caption under this photograph reads: "German Prisoners of War are taken away in Leeuwarden".
The location is the street named Demer
in Eindhoven.

Letter of appreciation

The correspondence between the historian and Tom was printed in
the 2005 compilation book with
"Letters to Dr. Lou de Jong."

The original 1983 letter

This is a scan from our archive of the prized letter from historian Dr. de Jong.

Proof that this street is actually in Eindhoven, is in our comparison photograph on this website under Now & Then, Holland.


Another example is this photograph from 1984, at the commemoration of the 40th anniversary of Operation Market Garden, when Tom met veteran Oscar Mendoza of "B" Co./326th Airborne Engineer Battalion on the Drop Zone near Son and got his autograph.

Mendoza made a parachute jump in 1984. He became immortalized in this photograph, taken in September 1944 near the bridge in Veghel.

Mendoza had injured his jaw but refused to be evacuated as a casualty. Instead, he commandeered a cargo
tricycle and collected A4-aireal delivery bundles that were dropped to resupply the 501st Parachute Infantry Regiment.

Tom's interest in World War Two never decreased and through the years,
He conducted research, collected artifacts, visited battlefields, archives and museums, attended reunions and commemorations and met numerous WWII-veterans. 

Tom is a member of the Friends of the Hartenstein Airborne Museum,

Life Member of the 101st Airborne Division Association,

Honorary Citizen of Clarksville, Tennessee; the city next to Fort Campbell, Kentucky, home of the 101st Airborne Division
and at the age of 50 decided to actually add "battle" to this detective and joined the Royal Netherlands Army as a reserve officer and currently has the rank of first lieutenant (NATO: OF-1).


On www.battledetective.com,the results of his research are published on-line.

Praise for Battle Detective.com

"[When] John Klein came to Normandy with Bill Galbraith and Manny Barrios to help Roger Day and me launch
Tonight We Die as Men, he unwittingly introduced me to a pair of Dutch historians, Tom Timmermans and Tom Peeters, who later became my research team in Eindhoven. Despite having busy careers and their own historical websites - www.battledetective.com and www.battleatbest.com - both men are a joy to work with and have helped me shape this book into a profound and meaningful historical record, that I hope everyone who reads will understand and appreciate.
