A better timeline

I have wanted to correlate the timing of events on the Eastern front of the war (where Teancum and later Moroni were) with those on the Western front of the war (where Helaman was after Moroni left). One thing I verified today was that Helaman began leading the stripling warriors before Moroni rejoined Teancum. Helaman started leading in the 26th year while Moroni arrived back on the Eastern front in the latter half of the 27th year.
