U vremenu pred smrt, razocaran i svojom licnom sudbinom, i karijerizmom, i korupcijom u zemlji, u svojoj skromnoj kuci na Topcideru, Rajs pise ratne memoare "Sta sam video i proziveo u velikim danima", kao svedocanstvo o jednom uzburkanom vremenu u Srbiji. Beleske koje je svakodnevno vodio, izvestaje srpskoj vladi i dopise koje je slao uglednim svajcarskim, holandskim i francuskim listovima, Rajs je sabrao u ovo jedinstveno stivo o Srbiji, srpskom narodu i njegovoj vojsci u Prvom svetskom ratu. I posvetio svojim saborcima iz teskih, ali slavnih i nezaboravnih dana.

Written in the twilight of his life, the Swiss criminologist who chose Serbia as home gathers field notes, dispatches and reports into a first-person chronicle of World War I. Reiss records occupied towns and retreats across mountains, the discipline of the Serbian army and the civilian courage he believed deserved the world's memory. Unvarnished and humane, this is both a historical document and a testament to loyalty and loss.
