Yes that's true, it did become sch in German and sh in English but those are separate developments, they didn't happen together. In Dutch something different actually happened but it may not appear that way if you don't know how Dutch is written. In Dutch, sch is actually two sounds, s and ch, not one like in German. In early Dutch the sound was still written sc (pronounced sk like in Germanic) but it softened into sch (s-ch, not sh), and eventually, a few hundred years ago, the ch-sound disappeared altogether whenever sch was not at the beginning of the word, so it became just s. At the beginning of a word it's still sch though.
