I was doing some reading on the Austro-Prussian war and how it was considered one the first modern industrial war in Europe, due to the extensive use of railroads, breech loading muskets/artillery, and also more modern supply and logistical methods. I know that similar tactics were used in the American Civil War though, including telegraphs and balloon aerial surveillance and before that some of this technology was used in the Crimean War as well. Are there any earlier examples of wars that say increased used of these technologies? I personally couldn't think of anything prior to the Crimean War (though the logistical blunders in that war should be noted).
