So it could be quite high too, and very similar to this one in April 1941 in combat against Yugoslavia.

The original English text of my book reads: A German intelligence report on March 27, 1939, gives the following summary account of the events: "In the morning of March 23, certain Hungarian detachments, advancing from the south and east, entered Eastern Slovakia from three directions. The advance came to a standstill on March 24. The line of demarcation occupied at the end of encounters would probably be, apart of minor deviations, 10-15 km inside Slovakia. About 100-150 persons were killed during the clashes and about twice as many wounded.”
Therefore, the total losses of all sides were estimated at about 100-150 soldiers killed.

If you check out Chapter 7, you will find the following info:
"In total, Hungary recovered 12,171 square kilometres territory as Sub-Carpathia. The Hungarian Army paid for this gain with seventy-two dead, 144 wounded and three missing."
