Concatenation of files using ffmpeg does not work as I expected. Why?

I execute the following command line for ffmpeg.exe -i C:\Beema\video-source\DO_U_BEEMA176x144short.avi -i C:\Beema\video-source\DO_U_BEEMA176x144short.avi -i C:\Beema\temp\9016730-51056331-stitcheds.avi
-i C:\Beema\video-source\GOTTA_BEEMA176x144short.avi -y -ac 1 -r 24 -b 25K C:\Beema\video-out\9a062fb6-d448-48fe-b006-a85d51adf8a1.mpg

The output file in video-out ends up having a single copy of DO_U_BEEMA. I do not understand why ffmpeg is not concatenating.

Any help is dramatically appreciated,
