A 900 mile long frontline from Kherson on the Black Sea north to Luhansk stretches Ukraine's forces along a long line in June 2023. A Ukraine effort to retake areas lost to Russia in eastern Ukraine and near Crimea as part of the counter offensive is only making slow progress because of land mines and lack of airpower. The successful Ukraine effort in 2022 to retake Kherson happened in an area which had two rivers and where Russia faced logistical issues of supplying its troops. In 2023 both sides have prepared for some time and it is very difficult for both.
