I have done extensive research on the 3rd Indiana Cavalry and I know of no photos of Company L. I do have some more information for you.

Company L was raised in October 1862, nearly a full year after companies A-K were raised (there were no company J designation in the army). This was because when the war began, cavalry regiments were ten companies. Two additional companies were added later by the War Department as a full complement for a regiment, so companies L and M were raised. They did not immediately go to Tennessee. The governor of Indiana was a powerful political figure and he was able to convince the Army that the two companies were needed in Indiana to combat the threat of the Knights of the Golden Circle - a suspected pro-southern group who were purported to be plotting the take over of Indiana for the South. As far fetched as this sounds today, it was considered a real possibility at the time. They were also used to arrest deserters and to enforce the draft. Neither of these activities were in favor with the population of Indiana!

When John Morgan raided Indiana in July, 1863, companies L and M were the only cavalry in the state and they chased Morgan all the way to the Ohio-West Virginia border to Buffington Island. The companies were sent to Knoxville in Oct. 1863 and operated in eastern Tennessee as a detached unit until January, 1864 when they joined the western wing of the 3rd Indiana Cavalry. They fought all the way to the end of the war as a part of the west wing. In January 1865, the remaining men of the 3rd Indiana Cavalry were consolidated into the 8th Indiana Cavalry, but men insisted that the colonel of the 8th preserved the organization of the 3rd and treated it as a separate unit for the remainder of the war.

The 3rd Indiana Cavalry fought as an eastern wing (companies A-F) in Virginia and Maryland while the West Wing (Companies H-M) fought in Tennessee, Georgia and Kentucky. Given the history of companies L and M, it can be argued that it had THREE wings for a time.

Hope this helps. I may have more if you want to contact me back channel.
